So often it's gardeners make great gardens not owners or designers



I recently had an upsetting email from a colleague and friend who has just had his last day at the job he has had for nearly twenty years. He feels forced out because of decisions made about his job, over his head, which will so change the nature of what he does so much that he no longer wants to be part of the garden he has worked on, and whose reputation he has played a big part in building up. It was his efforts and ideas that put the garden on the map as a very distinctive project; the management now have other ideas. It's a story you hear time and time again unfortunately.

Any look at historical gardens makes clear that the successful ones were where there was a head gardener and owner pulling in the same direction. Toby Musgrave's recent book on head gardeners makes this clear. Some head gardeners indeed rather tyrannised their owners. I can imagine a number of Victorian garden owners, Lord this or that, who might have been a great power in the land (and indeed over their tenants), dreading a meeting with their head gardener. The man's status (in charge of a large team), hold over the family (producer of all the fruit, vegetables and cut flowers, which his cook and crucially, his wife, would expect daily deliveries of as a matter of course), knowledge (all those Latin names) and demeanour, could combine to make Lord Whatsit feel very small and humble indeed.

Those days are gone, and head gardeners of large gardens now work with diminished staff and, it has to be said, status. The biggest problems are often with gardens that are open to the public, and therefore run as businesses. The head gardener here will have a major impact on income. If the garden is run on a charitable basis then there will be a trust to whom the head gardener will be ultimately responsible (or 'board' in the US). The role of a trust is to oversee the charity, ensure that it is financially successful, and fulfils all its legal obligations. A good trust has clear objectives, consults the staff and works with them to enable them to make a success of the project. All too often however, trusts are made up of people who may have been very successful in some walk of life but know next-to-nothing about gardening. They may like gardens, but if they have never had experience in getting thousands of bedding plants ready for going in by mid-May, overseeing the replanting of an entire border, or dealing with a fallen tree the day before opening, then they will inevitably need a good imagination, and considerable humility, in approaching the task of how to give advice to somebody who can do all of these things. From the perspective of the gardener, too many people on trusts are interfering busy-bodies who have no idea what they are talking about.

Maximising income is a key goal of a trust. This can of course be used as a weapon to drive through all sorts of changes, often in the direction of thinking that the more people you get through the gates, the more the garden earns. The great danger here will be 'dumbing down', bringing in events, or developing areas that are 'lowest common denominator', avoiding innovation, experimentation or any sort of trying to stand above the common herd, and therefore taking a risk. I think this is what might have happened in my friend's case; the trust want to increase visitor numbers: roses are popular: => more roses = more visitors = more income: never mind that roses will not grow especially well there (they haven't asked the gardener). Another garden I knew decided to try to get more families in by having a scarecrow competition; ok. I can imagine that in a garden that actually grew vegetables this might have been a good idea, but it wasn't; the result – droves of overdressed scarecrows in borders of perennials, poking up amongst shrubs, hoist in the rockery etc.; the garden ended up looking ridiculous.

Bringing in volunteers is a way of getting more work done in the garden that appeals to trusts. There is the feel-good social mission of using volunteers as well. But has the head gardener got any management skills? Quite possibly not. Well-managed volunteers can transform a garden; badly-managed ones can (and do) wreck chaos and destruction. I hear so many stories of head gardeners being expected to manage volunteers and not being given any choice in the matter. The worst was a National Trust garden that decided it would offer horticultural therapy and expected the head gardener to take on a variety of people with a range of 'issues' and help turn their lives around. No consultation. No offer of staff help from people who had any interest in therapy or knowledge of it. She left. 

Another mad idea that trusts or owners indulge in is that of getting rid of head gardeners altogether and replacing them with the occasional visit of a consultant. I got wind of one such job assassination once, it was even hinted that I might like to be the 'consultant'. Apparently it was going to save a lot of money. The feedback I gave was that I thought it would be a disaster, and anyway, anyone who took the consultancy would probably find themselves face down in a compost heap with a sharpened trowel in their back. The head gardener concerned had a national reputation; the garden has since gone massively downhill. What a surprise.

It is the failure to talk to and listen to head gardeners and their staff that is so unbelievably arrogant and foolish. In the case of the garden I started to talk about, the result will almost certainly be to kill off one of the most successful genuinely innovative gardens in Britain. It will become just another vaguely historic rose-packed garden scrabbling for visitor numbers in competition with all the others.

Australian plants amaze, astonish and confuse


The stunning landscape installation by Kate Cullity at the Cranbourne Botanic Garden, Melbourne, evokes the Australian Outback
Still mulling over my recent but brief trip to Australia. We'd spent most of our time 'down under' in New Zealand, followed by a week in Tasmania before a week in Melbourne at the biennial Australian Landscape Conference. This was a fantastic event, organised by Warwick Forge, a retired publisher and entrepreneur. I am sure the fact that Warwick is not a professional 'landscape person' has been one of the reasons for the success of the conference; an ability to see beyond immediate professional concerns and trends. It also probably helps explain why the conference was a real coming together of professionals, and some amateurs, from the world of horticulture as well as landscape. Gardeners and landscape folk meet together on equal terms all too rarely.

Warwick first approached me about speaking at the conference nearly two years ago. He does his homework well. Being a retired chap of independent means he is able to spend time traveling around meeting people and checking them out to ensure that the resulting two day conference and workshops really delivers passion, stimulation and knowledge. I remember we agreed to meet in Oxford and spent an afternoon wandering about the Botanical Garden, discussing what I did and what I knew of what my colleagues did. I remember Warwick asking me “if I invited you to speak, who else would you like to speak?”. I'm a ferocious networker so I was able to make plenty of suggestions. Cassian Schmidt was my first choice, the director of the Hermannshof Garden in the Rhine valley and increasingly a leading teacher of planting design through a post at Geisenheim University. Thinking of parched Australian landscapes however, I had to admit that what we had to say might be only rather partially relevant.

Shortly before I met Warwick, I had been in Spain and met Miguel Urquijo, whose ground-breaking approach to garden design in Spain and deep thoughtfulness about what he did, had really impressed me. So I told Warwick about him. A few weeks later I learnt that Warwick had more or less straight away flown to Madrid to meet Miguel. I had also insisted to him that if he invite Cassian he ask his wife Bettina Jaugstetter too, as she is emerging as a very interesting planting designer in her own right. She was asked to run two workshops, but of course she worried that “no-one has heard of me, so no-one will come”; apparently though, hers filled up before anyone else's – a strong indication that the reputation of contemporary German planting design has great pulling power. I wonder whether she would have got such a good audience in Britain? I fear perhaps not.

A real feature of the ALCs over the years has been the pre-conference speakers' tours whereby the speakers are crammed into a mini-bus to tour gardens and landscapes in the state of Victoria. The day we went to the stunning new botanical gardens at Cranbourne, and then Kuranga Nursery was a memorable one. For me it was a meeting with old friends.

Banksia marginata
A zillion years ago, in the late eighties and early nineties, I had a small nursery business near Bristol. Mostly growing perennials. Which, for the youngsters amongst the blog-readers, were not particularly widely grown at the time - astonishing though this might seem to you. But, I grew a rather zany range of half-hardy stuff as well, with a particular focus on Australian plants. The reason for this rather eccentric choice was that there was a sudden fashion for conservatories but hardly anyone growing plants for them. Most of the new conservatories popping up featured little more than a dehydrated Ficus benjamina and a few spider plants. Looking at the prevailing conditions and doing a bit of research into what the Victorians grew in conservatories, an obvious choice seemed to plants from southern Australia. Important was the ability to cope with occasional high temperatures and lows to near, or just below freezing. 

Xanthorrhoea australis - the Grass Tree, at Cranbourne
The idea of actually using your conservatory to grow plants in never took off, unfortunately, and today many conservatories, if they have any flora at all, are still likely to have only a dehydrated Ficus benjamina and three spider plants. However, I found myself selling plants to many people in the South West, including some heritage gardens like Tresco which had had some bad winters and needed to replenish their stocks. I used to trek up to London every month to set up a stand at what were then the monthly Royal Horticultural Society shows. Although the Australian and other exotica were only a small part of what I grew, they were a useful flagship for getting interest in the nursery and publicity generally.
My choice in growing the range of plants I did had been bolstered by researching (in the RHS library) what early 19th century gardeners grew. Early glasshouses and conservatories had pretty primitive heating systems, which produced dry air and often failed. The technology coincided with the botanical exploration of South Africa and Australia, and gardening journals of the time are full of beautiful hand-coloured prints of Cape Heaths (Erica species), Australian Banksias and Melaleucas. So it was these that I focussed on growing. Seed was easily come by and they germinated easily enough. Well, I grew the ones that were easy to germinate – there is a whole tranche of Australian flora that is notoriously difficult from seed - I never bothered with them. Species of Banksia and Dryandra from Western Australia were particular favourites, both with myself and the public at the RHS shows. With tough, slightly silvery leaves, often looking as if they had been cut with scissors, and extraordinary flowers that looked and felt like plastic, they seemed like plants from another planet. Tending to be small and compact, they were ideal as container plants. Perfect 'talking point' plants. However the Australian literature on them at the time stressed how difficult they were to grow. As it turned out, this was a reflection of the fact that species from the Mediterranean climate of Southwest Australia did not adapt very well to the humid summers of the southeasterly states of Victoria and New South Wales where the majority of the gardening population live. Adapted to soils of extreme infertility they did not like conditions in 'ordinary' soil either.
Banksia blechnifolia - the flowers mimic hair curlers -its officially a shrub by the way

Growing many of my 'Australians' in a mix of three-quarters sharp grit and one quarter peat, I found Banksia and Dryandra thrived, flowering in three years. Doing better in a richer compost were various species and cultivars of Callistemon, Melaleuca and Correa. Although I failed to displace the sad-looking Ficus benjamina and spider plants from the conservatories of England, something else happened. People started buying the these plants and sticking them outside in sheltered places. Many did very well in coastal Cornwall and Devon, or even inner London. The 1990s saw milder winters, increasing importation of southern hemisphere species and a taste for 'architectural' plants, bringing about radical changes in what we grew.

Back to the ALC speakers' outing. At Kuranga Nursery we saw the largest range of Australian native species commercially available. For me it was thrilling, never having been here before, to see so many of these plants growing to full size. I have not grown any of these for years, but seeing them brought back a rush of memories. And reading names on labels, particularly where I had read about genera that were 'impossible' to grow from seed, and seeing the plants for the first time, was a real thrill.

Others on the tour were perplexed. It was particularly funny watching Cassian and Bettina, who, being from Germany, are unable to grow any of this outside, had no familiarity with anything they saw. They appeared to be completely disorientated, truly suffering the shock of 'arriving on another botanical planet'. The fact that so much had a superficial similarity with the familiar, added to the disorientation. Plants from dry environments have a strong tendency to look the same, but then surprise by producing exotically different flowers to their northern hemisphere look-alikes. At one point Bettina came up to me waving a plant in a pot, “it looks so much like a cistus” she exclaimed, “but it isn't, the name means nothing to me”; she looked genuinely upset. Cassian was complaining about families he had never heard of. Densely-packed sales benches offered novelty, thrill and disorientation in equal measure.

I'll leave with two little snippets. One was the thrill of seeing Epacris for the first time. A genus of heather-like plants (all Epacridaceae have now been disgorged into Ericaceae by the way) these appeared to have been very popular throughout the 19th century. Winter-flowering, they must have been easy to propagate from cuttings as they must have been widely sold as flowering pot plants, and given what can be read about their cultivation in Victorian gardening journals, often kept from year to year. There were around twenty or so named cultivars. And then they vanished. When I had the nursery I was never able to source seed. I never even saw one at Kew Gardens. Seeing them on this trip was the first time I had ever set eyes on them. Roger Elliott, the leading writer on Australian natives who accompanied us on this trip did explain that there is a great deal of variation in flower colour, which was probably one reason for their popularity.

Epacris impressa
Finally, Dryandra. When I grew these at the nursery, I was struck by the extraordinary scent of their flowers. Sweet, exotic, quite unlike anything else. No mention in any of the literature about them. Leafing through a couple of more recently-published books on the well-stocked Kuranga Nursery shelves, only the most minimal mention. Perhaps they are only fragrant abroad.

The New Zealand look - the colony's revenge?




First time in New Zealand. Which is a bit like arriving on another planet in plant terms. But not others – very strange travelling such a long way to arrive somewhere s
o white and anglo-saxon, although the Maori gets many a respectful nod in wayside or visitor destination interpretation. Its a fascinating place to appreciate plants in a very different way to what we Northern Hemisphereans are used to, but also to consider the human impact on landscape and environmental history. The following is obviously a brief first impression.


To start with, the aesthetic quality of the flora is so totally different to anything we know from the northern hemisphere, in evolutionary terms it is a very old flora derived from a tropical origin: all very graphic, and textural: tree ferns, Araliaceae, big grasses, Phormiums, and overwhelmingly evergreen and woody. Almost no perennials and almost no colour. Green, green, green - again, very tropical. No herbaceous softness. Our northern hemisphere flora must look very dull to a Kiwi, despite the colour of our flowers. It's a flora which looks amazingly neat and almost designed – at one point Jo pointed at some plants by the side of the road and exclaimed “it looks like some posh garden designer's been in and done it all”. 

Blechnum novae-zelandiae covers a great many near vertical rock surfaces

On the wet south and west coast of the South Island it is the cryptograms (non-flowering plants) which are so amazing. This is the Land of the Fern. So many species. Big, tough muscular things, All-Blacks rugby-playing plants, not like our flimsy-mimsy ferns backhome. Coating banks, retaining walls, even replacing grass as a sunny habitat ground cover. Filmy ferns in the woods, all the way up trees. They are the ones with leaves only one cell thick, so you can see your hand through them if you hold them. Mosses, foliose liverworts and lichens of an unbelievable size. Club mosses up to a metre long dangling down banks or off trees. And the ultimate botanical nerdy treasure - Tmesipteris, a living fossil, with virtually no close relatives. Its like tripping: you just stand and stare at everything in a hypnotic botanical trance, the sheer level of diversity in a few cm2. is mind-blowing. Things I have never seen before, even on super-wet Yakushima (Japan) or the tropics, like weird mounds of vegetation which form over rotting timber or huge mossy lumps, a metre across, way up high in trees, or astelias or pandanus-relatives coating entire tree trunks with what looks like superisize grass. But almost no flowers, at least visibly. On our travels, admittedly in late summer, there were red metrosideros flowers and a teeny-weeny orchid and that was about it. 

New Zealand's geological history has isolated it from the rest of the world, so plant evolution took off in a direction that was quite different to anywhere else. Its human history has been very recent, compared to the rest of the globe, and its impact on the natural world here has been sudden and drastic. Pioneers are very often rapacious in their exploitation of the novel environments they encounter, and New Zealand had the misfortune to get a double whammy within a few centuries. Polynesians arrived in around 1250, ancestors of the Maori, and as they did across the Pacific, ate their way through local bird populations, here wiping out the moas, enormous flightless birds that were the key predator of many plant species; as well as burning down much of the forest. British settlers arrived in the 19th century and proceeded to fell every tree they could get their saws into and destroy vast areas of natural habitat to make way for sheep. Adding insult to injury to the ecology they decided that the country was to be a 'new Britain', and imported a whole suite of British wildlife, including various predators like stoats and weasels, which then ate their way through much of the remaining birdlife.

One of the odd things about being here is the extreme disjuncture between genuinely natural and 'created' landscapes. There are huge areas of pretty well untouched wilderness, a lot of it along the west coast, mainly terrain that must have been too steep too log. Because of the wet (we are talking metres of rain per year) this is the part of the country that is so insanely biodiverse, especially for ferns and other 'primitive' plants. Much else, especially along the east coast or the south is a very functional agricultural landscape, with almost nothing native to be seen over huge stretches. Pasture grasses (a European import), and imported tree species and that's it; the absence of anything original is quite bizarre, but then there was almost nothing in the native flora which was herbaceous and could have integrated itself into this agricultural landscape. In North America, by contrast, also a continent colonised by European pasture grasses, local wildflower species survive along roadsides in even the most ag-intensive places.
Sticherus cunninghamii, Umbrella Fern

There is an irony here. Just as much of New Zealand has been turned into a copy of a European landscape (albeit a very functional one) we seem to be determined to turn our designed landscapes into a copy of New Zealand. I'm not just referring to the large NZ component in our landscaping plant flora; in rough order of widespread use: hebes, phormiums, cordylines, pittosporums and brown Carex sedges, but to the fact that what we want in an urban landscape – evergreen, compact, predictable, interesting foliage, is what much NZ vegetation looks like. As climate changes and it becomes practicable to grow more NZ plant material, then I am sure this proportion will increase.

British gardeners fell in love with hebes as soon as they began to arrive in the early 20th century (but they were then classified as Veronica) and the first hybrids were exported back to NZ. They are ideal for windy mild climates, like the south and west of Britain; the rest of Europe and the US, not surprisingly showed no interest in them. Pittosporums and various other NZ plants appeared during the same period but tended to be restricted to Cornwall and other benign climates. Then in the 1980s container loads of NZ propagated plants were imported wholesale and we had more to play with. Phormiums took off almost immediately, and I remember developing something of a dislike of them. They suddenly started appearing everywhere, often in places that were quite unsuitable, and what was once seen as a rather magnificent exotic plant seemed in danger of becoming a cliché. The same could be said of Cordyline australis in gardens, which began to make big inroads with the arrival of milder winters and the growing trend in 'exotic' and 'architectural' planting, during the 1990s. For those who could afford them, tree ferns (mostly in fact Dicksonia antarctica imports from Australia), began to sprout too in sheltered London gardens, although London is really too dry for them to be a serious long-term proposition. They look far more at home in Cornwall or west Wales where they are much more at home (and can even 'seed').
Pachystegia insignis - one of the hunky-chunky windproof species so evident in the NZ flora

Other NZ plants began to appear at the same time, but did not make much of an impact. Although a lot of the flora has that chunky, graphic look, there is also a lot which, almost as a contrast, is quite the opposite: shrubs with very fine-textured foliage and very dense growth. The distinctive growth pattern of a lot of these may well have been an adaptation to reduce attractiveness to the extinct moa birds. Coprosma, Pseudowintera, Corokia, all known perhaps to the (woody) plantsman, but none have made much of an impact. There being evergreen and having such neat shapes seems guaranteed to endear them to us. Looking at some of the denser coprosmas, rather a pity I think, as they look to me as if they could be the best replacement for pest and disease prone box yet. 


Quite the opposite of the above - a small-leaved Coprosma species makes a bril hedge - possible box substitute?
What did not appear much in the 1990s and have still to make much of an impact, surprisingly, are a whole suite of Araliaceae. Like all members of the ivy family, they start off with one leaf shape and produce another at maturity. Many of us may be familiar with Pseudopanax crassifolius, and of these many of us probably rate it as the ugliest plant out; however its juvenile 'is it dead?' leaves are probably an adaptation against moas too. Others are more 'normal' looking and I'm surprised more have not shown up in British nurseries and gardens. For those looking to increase the distinctive foliage look in their gardens there is an awful lot to learn here and try out, whilst at the same time reflecting why it is that 'we' (Brits at any rate), having done 'our' best to turn one place into another Britain, we are now determined to make our urban landscapes as much like New Zealand as possible.

Singapore's Garden Extravaganza - with a focus on cloud forests



The last time I was in Singapore which must have been getting on for ten years ago, Gardens by the Bay was under construction. The roads near the Marina were lined by trees in enormous containers, making you feel as if you had just driven into a garden centre or nursery that catered to giants. All were destined for one of the world's largest and most ambitious horticulture projects.

So, the first thing on re-visiting, was to get down there and see how the project was doing. The first impressions were very much that this was opulent public horticulture, walking a path between well-funded amenity horticulture and something more educational, but without any pretence at it being a botanical garden. Spectacular constructions, such as the signature 'super trees' and huge scale plantings make a powerful impact, but don't help define quite what the garden is for, other than impressing the visitor. Public gardens have often had this role. In trying to make sense of this extremely large, very well-funded and ambitious project it helps to think back to the Victorian era.
One of the Supertrees
In that golden age of gardening, public parks were about municipal pride, and declaring the status of the city or community that funded them. Not much chance of that happening in today's Britain, the most centrally-controlled country in Europe, where local government is so squeezed by the politics of austerity that basic services are beginning to break down. Singapore, like other successful Asian economies, are in a similar situation to where we were in the Victorian era. With its reputation as a garden city (an inheritance from the British Empire) and the world's leading centre for urban greening, the use of gardens as a national icon seems natural.
These are dogs, since you ask. It is the Chinese Year of the Dog this year.
The scale and level of control is all a bit overwhelming. The control is again, very Victorian, and likewise dependent on cheap labour (mostly south Indian Tamils). It is also very Chinese. Singapore is the ultimate state run on Confucian lines. “We think of the government as being like our parents” says a Chinese friend (and no particular fan of her government in Beijing and in fact having deep personal reasons for thinking quite the opposite). 'Planning' and maintaining control have been key to the city-state's (amazing) success as an economy. Nice tidy public gardening on a mega scale is all part and parcel of a paternalistic state which wants its citizens to enjoy their spare time in suitably safe and unthreatening ways. Its not somewhere where many western liberals would like to live, but it's the only place I have been where multi-lingual poster campaigns invite people to grass up their employers if they face unsafe working practices.
See those little figures down in the bottom right? They give you some idea of the scale.
Possibly inspired by, or aiming to go beyond, Cornwall's Eden Project, there are two vast 'greenhouses', kept cool rather than warm, using a clever heat-exchange system powered by decaying compost. We went into the Mediterranean one first. Here there are some good displays based on the various Mediterranean climate zones around the world, and good interpretation. Trouble is, someone's been unable to stop themselves having a go at some of the shrubs with their hedgetrimmer. There's a terribly kitschy faux-Chinese garden, planted with loads of forced-looking dahlias.

And then, the other 'biome'. Something completely different. Dedicated to cloud forests, this is the most sustained, visionary, high-investment naturalistic planting extravaganza ever. One of those things that gives one real hope. I'm assuming most readers will know what a cloud forest is, but for those who don't it is a mountain region that gets very high precipitation, much of it from being in the clouds. Cloud forests are biodiversity hotspots, often with very high rates of evolution, as every mountain side and valley will have slightly different conditions and the physical fragmentation of the territory allows for isolation and evolution. Think orchids, bromeliads, vireya rhododendrons, tropical begonias. The Gardens by the Bay Cloud Forest biome sends its visitors up in a lift to descend on a vertiginous series of aerial walkways around an artificial mountain covered in plants growing practically vertically.Vertical planting has had a bit of a chequered career in the temperate zone, but here, in a cloud forest zone (real or artificial) a lot of species grow like this naturally.

The standard of everything is just so high, the interpretation spot-on, with firm and imaginatively-driven messages on conservation and climate change. Given that we are entering the Chinese century, it is really encouraging to see such conservation leadership coming from within the Chinese language community.


Lycopodium and Huperzia species, club mosses - fern relatives. Having such botanical curiosities shows just how serious they are here about their plant diversity.

House Plants are back!




After many years of being seriously uncool, house plants seem to be back in fashion. My son, more in tune with the zeitgeist than I (after all he lives in Clapton in east London – Clapton-the-new-Brooklyn (but hasten to add is NOT a bearded hipster) has started to pack his windowsills. A few trendy looking books have started to appear as well, usually in furnishings and accessories outlets that don't generally sell books, which is always a sign that something is 'on trend'. 

I have long been puzzled by the lack of interest in house plants, particularly amongst dedicated gardeners. So many really good plantspeople seem to suspend all interest once they step inside the house. I am always slightly surprised that a lot of good gardeners and plantspeople don't grow their own veg, but then not everyone is a foodie and growing things to eat is very time-consuming and requires a lot of organisation, so I more or less understand that; to turn from weeding the Arisaemas to nipping down to the local supermarket to busy some packeted veg. is understandable. But not to grow anything inside? I am genuinely puzzled.

For myself, and I think for quite a few gardeners who started in their teenage years, the first plants we grew were indoor ones. Tropical stuff, cacti, orchids, insectivorous things, kinda adolescent slightly nerdy things. Most of us then soon moved outside, but the love of plants on windowsills or atop cupboards has never left some of us. 

Those who started as 'outside gardeners' don't often seem to be able to make the transition to keeping plants inside. One reason might be the sheer artificiality of keeping plants growing in what is, after all, a very alien environment. The quality of growth that it is possible to get from plants growing in the ground is so much more difficult to achieve from indoor plants. House plants are incredibly dependent on their owners and keepers for their most basic needs. Many plants also respond to seasonal changes, primarily to temperature, and since we humans seem happy only if we are kept at around 21ºC that limits possibilities. Small failures build up, and if things go slightly wrong, we are then stuck with a below-par plant which given the shortage of spaces to grow plants in most houses, is always on view. We are then constantly confronted with evidence of our own failure as gardeners in other words (and the horti-social embarassment).

The hard fact is that there are not very many plants which grow well inside. Light levels are generally too low; dry air is also often a factor that affects plants badly. Succulents do well, but only if they have really good light – so unless you have extensive sunny windowsills there is not much habitat for them. The range of houseplants which was developed during the 1960s, the high point of house plant history, was a pretty limited one. Essentially it built on what I call the 'aspidistra concept', the very idea being one which has been one of the factors which has limited interest in them over the years anyway. It was the Victorians who really were the pioneers in growing house plants, despite the fact that their homes were infamously dark, with big extremes of temperature and polluted (coal smoke pollution inside and out was horrendous in the 19th and much of the 20th century, making today's worries over diesel exhaust seem almost like minor niggles). 

Aspidistras survived the grim growing conditions of the Victorian home, along with a limited range of other, it-has-to-be-faced, rather dull plants. They grow incredibly slowly, with very long-lived leaves. They are as near to static and plastic as plants can be. The aspidistra is a plant of deep shade, where resource inputs are low, so it grows immensely slowly. Ivy (Hedera helix) will survive similar conditions, and of course if conditions are right, can move pretty fast, but if poor can just survive, for years; not surprisingly it too was common in the Victorian home. Much of the 1960s house plants were visually more exciting but in many ways not much better, many being tropical forest floor plants – happy at 'our' temperatures, but able to survive for long periods without growing much: Philodendron, Monstera, Aglaeomena, Anthurium – all tropical Araceae. If they do start to grow their new growth is often weak and unattractive. They are not really living plants, in the sense of something which grows and develops.

I did do a house plant book once – a long time ago. Unfortunately all packed up, which given my current peripatetic status is going to be the story of my life for some time from now on. So I can't share pictures, but will try to do so in a future blog. In researching the book, we did find a few people who had examples of the kind of plants I have been just discussing, but which had been cared for well and had actually grown pretty spectacularly. There was a Rhoicissus which had colonised the hallway of a substantial north London house (actually part of the family) and an enormous Swiss cheese plant (Monstera deliciosa) in a Liverpool sitting room (ditto, belonging to the late Tony Bradshaw, the botanist and ecologist). 

The static nature of much of the conventional house plants flora must be one of the main reasons as to why few 'real gardeners' can be bothered with them. Plants which grow more vigorously, in particular those which flower, generally need more light than we can give them, or many of them. An exception might be orchids, which are relatively common as house plants now, all but unknown as such forty years ago. And of course, gesneriads: Streptocarpus, African violets, Achimenes. Small, relatively quite fast growing, not needing too much light (good indirect is best) and often usefully dormant for part of the year, gesneriads are an amazingly diverse and fascinating family. Their slightly hairy foliage and compact size give them a sort of cuddly, teddy bear quality too. When I'm in my dotage, I shall surround myself with them in the old folks home.

Our houses are actually very badly designed for plants – another problem facing the 'home' gardener. There were some attempts in the 1950s and 1960s in Sweden, a period and a place for particularly bold re-thinking of the domestic environment to create houses with small integrated growing spaces. The only one I have ever actually seen was, I think, at Beth Chatto's, a modernist 1960s design. I have often had the fantasy of designing a house around growing spaces for plants: light in just the right places at just the right amount, small planting beds strategically placed. There is a disadvantage perhaps to having too much vegetation around: the dead leaves, flowers, occasional insect pests, all add to a confusion of housework and gardening. I suspect it was this dislike of 'mess' which so restricted the use of plants in the conservatories of the 1980s conservatory boom. Victorians loved conservatories but had lots of cheap labour in the form of servants to attend to the cleaning, picking up and primping. 

So, its good to see house plants as 'back' but I can't help feel that we could do so much more.

Thanks to my son, Kieran Bradshaw. for the pictures.

Portugal's firestorm disaster - eucalyptus to blame

This is the old manor house which Jo's daughter and family were thinking of buying, but the estate agent hadn't updated the pictures.


There was a day last year, October the 15th, when the sky over southern Britain turned an apocalyptic orange – we knew that the remnants of a hurricane, Ophelia, was about to hit us, but it was not until later on that we learnt that the extraordinary light conditions were the result of soot from fires in Spain and Portugal. Forest fires on a massive, and so far unprecedented scale for Europe. Having just spent a couple of weeks in the affected area, and concerned that there has been very little publicity about what happened outside the region, I want to say something about the issue here.

There had already been severe fires in Portugal in June, and a blog posting of mine then had discussed them in terms of them being largely the result of extensive eucalyptus planting. The conditions in October were exceptional: Ophelia was the most easterly tracking hurricane ever, big storms rarely go that far south, and the region was tinder-dry after many months without rain. All of these are indicators of a possible outcome of climate change.

Words cannot even begin to describe the scale of devastation, which has had nothing like the international press coverage it deserves. It looks as if someone has taken a flame-gun to the countryside. It is possible to drive for several hours across central Portugal and nearly every area of forest or trees in villages or in farmland have been burnt. Many houses too, especially the rather splendid big old abandoned houses which this country of large-scale rural depopulation is littered with. Some factories and warehouses too. Parts of the country are like a war zone. The Avo valley, a steep river valley, once very picturesque despite the ever-present eucalyptus is now a blackened ruin of a landscape. All in all, a terrifying presage of what might become much more common with climate change.


Eucalyptus acted as a vector for the fires spreading them into areas of pine (also relatively inflammable) and other areas of woodland. There is very little deciduous woodland left in central or northern Portugal, and oddly a lot of oaks loo relatively damaged. Deciduous trees like oaks and chestnuts are not so inflammable. Indeed where there is deciduous woodland, it seems as if the fire has not penetrated.

Fire is an important part of ecologies in many regions and the idea that it is always bad and damaging is now rejected. Understanding it is vitally important as to how we manage landscapes and indeed plant gardens.

There are many 'fire-resistant' trees. Eucalyptus however the opposite, as they appear to deliberately court fire. This is what makes them so dangerous. I'll try to explain.

Think of Pinus pinea, the umbrella-shaped Stone Pine of the Mediterranean – its shape is obviously designed to keep the foliage canopy up and away from ground fires. Cork oaks are similar, and of course have the amazing fire-resistant bark which has long been one of Portugal's main exports. Pinus palustris, the Longleaf Pine of the American South does not have this shape but gets its foliage up from the ground very quickly. This latter and its relationship with fire is now recognised as having been fundamental to a vast swathe of land from North Carolina around to the border with Texas (most was felled in the late 19th century to make way for slave-grown cotton). Longleaf dominated its territory, but by leaving a big gap between the ground and the canopy allowed ground fires to sweep across vast areas doing little damage to the trees. The regularity of the fires ensured that there was no build up of fuel – many of these fires were probably like prairie fires, very superficial. They would however have damaged many tree seedlings but left the better-adapted Longleaf seedlings. However it enabled a very diverse grass and wildflower flora to flourish.

I first heard about Longleaf when I went to a lecture by Janis Ray at the university of Athens, Georgia many years ago. I thoroughly recommend her bio –'Ecology of a Cracker Childhood' 
and indeed anything else about this remarkable tree that you can find.


Key to the survival of all these species is to have small and frequent ground fires. This makes canopy fires rare, and it these that do the really lethal damage to mature trees. Pines do not survive, and generally only do so through their seedlings taking off after a disastrous fire.

Eucalyptus however seems to deliberately encourage canopy fire. Their bark peels off and falls off in great strips, leaving a pile of what amounts to kindling at the base of the tree, with some loose strips leading thoughtfully up into the canopy of oil-soaked leaves. They are a recipe for the smallest ground fire leading to an almost explosive canopy fire. After which they recover, remarkably quickly. Sprouts can be seen surprisingly far up blackened trees only months after burning. In other words the trees' burning seems an evolutionary adaptation, that knocks back other tree species and gives the eucalyptus a competitive advantage. Just the same as with grasses, which burn easily, but survive and flourish amongst more seriously damaged woody plant seedlings. 

To add insult to injury, young eucalyptus seem almost unaffected by the fire - presumably the canopy fires sweep over the top of them. I wonder too if the silver foliage they have is somehow fire-proof. 

I wrote about the origins of the Portuguese eucalyptus problem in this posting. Only to add that I have since found out that Portugal was massively deforested in the 19th and early 20th century by a combination of overpopulation and traditional agriculture linked to a failure to industrialise. Zillions of sheep and goats roaming the hills eating tree seedlings apparently. That linking of population issues with unadaptive agriculture and failure to develop sounds like today's Haiti or Rwanda. That's another story.

Transplanting myself, or is it uprooting?


One of the last pictures I took at Montpelier Cottage.  Late September.
“I felt so shocked I shut the computer right away and could not get over the news ” wrote a friend when she read my email telling her that we were planning to move. It has of course been a very difficult decision, perhaps the most difficult of my life. So many people who come to visit or stay remark how lovely it is, not the garden so much as the setting (a shallow valley, with woods on one side and no sign of human habitation) or if they mean the garden it is clear that they mean it in its rural setting. “Paradise” is the word often used. So how can we bear to leave?

Paradise of course is precisely that, a non-earthly place, where the garden-of-Eden maintenance was presumably done by angels, or some of the clouds of cherubs which infest Baroque churches. Earthly paradises are hard work. People have often wondered at how I have been able to juggle my varied, disparate and complex workload and garden. The answer is that I have been increasingly unable to; we have had a wonderful one-day-a-week gardener, Diana Sessarego, but I really needed more of her time to really achieve what I wanted, or someone else's, and we couldn't afford that.

Back last June, I wrote a blog post which flagged up our moving plans. We have now made the painful wrench, renting the house to a friend until we decide what to do. We are in for a year of travelling - a trip to New Zealand and Australia, culminating in my doing a presentation for the biennial Australian landscape conference. The rest of the year, I will be in Portugal for much of the time, which indeed is where I am writing this. As flagged up in June, we are seriously considering moving ourselves here.

“Life, and parties are best left too early than too late” is something that I read recently. I would add gardens. In my career of garden journalism, I have all too often visited gardens where the owners have clearly been unable to manage what they originally set out, or had simply over-extended themselves. I have usually found these quite depressing places. Reality unable to match the dream. Only rarely do gardens manage a dignified retreat. In truth, given my main focus being the naturalistic, I could probably do just this, and find it a very interesting and satisfying process. But I, or I should say we to include Jo, do not want to.

I am in many ways an experimental gardener, interested in how plants work, and work together. Once a certain point has been reached, things begin to plateau out: I feel as if I am learning less every year. I'd like to move on to new things. And new plants of course; there is always the plantsman-thrill of trying new plants and there is nothing like being in a new place for having to try new plants simply because of it being a different environment. At a time of changing climates and weird weather, it is important to learn more about drought, resilience to extremes, heat tolerance. Which is part of the thinking about spending some time in a Mediterranean climate.

We've had friends round to dig plants up, particularly rarer varieties which I worry may be lost to commercial cultivation, apart from it just being nice to share plants. I've also been able to distribute plants for some research plots, versions of the plots I have had for the last seven years and which have been a great way to trial plant combinations and learn more about how plants survive and interact over time. That has been a very positive outcome of moving, and the idea of trying to recruit other gardeners into running trial plots as a way of documenting what we learn about plants is something which I think I may well devote quite a bit of time to over the next few years.

Another reason for moving, or even forcing myself to move, is that staying in one place is actually quite limiting. One tries to grow Dicentra a few times, they fail every time, conclude that the soil is unsuitable and that's it, you don't try them again, so we never get to enjoy Dicentra or learn any more about it. Geranium endressii and its pink pals all grow like crazy in Herefordshire, that for me is 'the normal', and so much gardening has to revolve around how to manage or make the most of these plants; that they may not do so well elsewhere becomes a rather alien concept – but that will be the norm for others. Gardeners have traditionally very much been people who have stayed in one place, but as someone who has become a globally-orientated teacher of gardening and related skills, staying in one place has become to seem dangerously limiting. One of the biggest problems in garden writing I think has been the assumption that because it works for me, it must work for everybody, so that's what I'm going to recommend, and drone on about it all the magazine articles and books I write. This way we do not learn but spread self-centred myths.

There is something to be said for getting down on hands and knees in lots of other peoples' gardens, appreciating how plants grow in many different places rather than endlessly in one's own. It sounds like I am arguing for a future rather peripatetic existence of poking around other peoples' gardens. For how long I would actually do this before succumbing to the inevitable temptation of wanting my own plot again I don't know. I suspect probably not that long. We shall just have to see.
