The other side of work I undertake in the Middle-East region (other than tree consultancy) is planting design, for creating new landscapes always brings me a special joy. When they are in public spaces, I love the chance it gives to interact (albeit remotely) with many people in place, over time and hopefully, enhance their enjoyment of that place. In the public realm, what that place is, is being questioned and challenged in the light of urbanisation and climate change. Ecology and environment are driving design as never before.
I am about to start working on a collaborative project in Saudi Arabia. It will involve the specification of many trees, shrubs and groundcovers and I get to find out just how many locally-sourced big specimens I can find that are of acceptable quality. Much of this will come down to the application of formative pruning in the nursery and I’ll be on the lookout for the best available in the region. I suspect I’ll be sourcing a lot from neigbouring UAE, simply because of familiarity of sources. Quality remains a challenge, though.
My most pressing concern I have is how to improve on irrigation techniques, which are traditionally massed surface drip lines onto marginally improved sand. This is inefficient and wasteful and I shall be looking at the use of moisture retention mediums and sub-surface irrigation. I believe most watering of landscapes in arid climates could be cut by half, just by more efficient application and retention, in the right place. The picture above shows typical wastage in a Dubai suburban landscape.
Whilst urban planting requires urban plants, I will also be looking at the use of more climate-adaptive species, which I think is important in an era of climate crisis; the Middle-East is going to struggle to cope with every degree of temperature increase. The use of more desert-adapted planting is not new, and not applicable everywhere but I believe there is much scope for experimentation and new thinking.
For me, planting design is about building communities, layering types of plants together in harmonious associations that fit. I don’t mind grouping plants together that come from different geographical regions, but they have to come from a similar ecological niche. Such design is so much more than just nice foliage contrasts and I believe the results can be subtle, but profound.
Landscape must, of course, fit our purpose but I believe we tend to pursue this end to the exclusion of everything else. Nature is the basis of landscape, and so too is ecology, ecosystem and planet. We should not divorce our landscapes from this reality; rather, they should always seek to remind us of these connections. So yes, in town centres and urban streets, we have our eco-bling landscapes; vibrant places, exotic, heady, purfumed, exciting. Nature at it’s most unbelievably flamboyant (cue pic: delonix, the flamboyant tree). Elsewhere, we need more grounded landscapes, more real, more connected to place.
I love this tree, it is everything I have described above, pure eco-bling. Yet it is not appropriate everywhere and because it has become a part of the standard landscape palette, I belive it is overused, and used in places where other species would be more appropriate. I think there are many trees and shrubs that could be used in the region that haven’t been tried yet, from East Africa, for example. The climate there may be more equatorial and more varied but it is not so remote or different as that of some exotics imported from sub-tropical climates (the Delonix mentioned above is from Madagascar, again not too dissimilar).
I think planting design in the Middle-East faces a whole new range of
challenges and opportunities. The changing climate will force new
thinking, to match the new development and the new understanding that is
emerging of our intimate relationship with nature. I’m hoping to
contribute towards that new expression and understanding.
The world is finally, at the last minute, waking up to the impending effects and consequences of climate change. In the scramble to work out we must do (apart from the obvious cessation of burning fossil fuels), one thing, one factor is looming large: we need to put carbon back into the soil, where it can be stored indefinitely, and we need to reforest the Earth. Much of this is in the agricultural realm but there is a huge amount that can – and must – be done within the landscape and horticultural sectors.
Horticulture has a MISSION, it just doesn’t realise it yet
At the centre of this is good soil husbandry, something that we have largely forgotten about. Modern agriculture bypasses all need of soil health by chemically feeding crops; no need for microbes, nutrients, humus, mycelium or earthworms. Chemical fertilisers and herbicides bypass the lot. Most of our soils now are depleted to the point of useless by chemical farming, exacerbated by the tradition of ploughing, which causes erosion from rain and enables much of the soil carbon to move back into the atmosphere.
So whilst we need current global models of food production to transform into regenerative agriculture and agroforestry, we also need to look at our urban landscapes and gardens, and create a new design ethic, a new paradigm, even. I can’t deal here with agriculture but I have been thinking long and hard on what the landscape and horticulture trades need to do; fortunately, I believe there is a lot that we can do.
We need to envelope our existing horticulture trade within ecology, to create an “environmental horticulture” You could also call it ecological, resilience or regenerative horticulture. We (those of us in the trade) know that as a profession, the training of both horticulture (growing) and landscape (doing) are in decline. Horticultural colleges have shrinking budgets and often get the less ambitious or capable students; after all, who is inspired by the prospect of strimming verges or hedge-trimming another unloved carparking lot? Yet last year’s report by the Ornamental Horticulture Roundtable Group valued horticulture at £24.2 billion in GDP in 2017. That’s not inconsequential, yet it goes unrecognised. Fortunately, there is a way to make it much more enticing to prospective students.
Horticulture has a MISSION, it just doesn’t realise it yet. That mission is to adapt our urban landscapes and gardens to cope with climate change, to mitigate temperatures, water flows, to grow biomass and regenerate soils back to health. Healthy soil is the foundation of life, of all life, including our own. Good soil holds fertility, water and carbon. Yet who amongst us now knows much of soil science? Who designs landscapes as ecologies, as “novel ecosystems”, who chooses plants because they have these abilities, not just for pretty flowers? Who designs plantings for their biomass harvest, for creating mulches to feed the soil?
In this respect, I don’t believe it’s necessary – or right, in fact – to work with native plants only. What is native? What was native? What was here 11,700 years ago when the last glacial period ended and the glaciers retreated? Flora and fauna move around the globe all the time, they are opportunistic, not fixed permanently into some tightly integrated ecosystem. We know there is no “ecological climax”, no ultimate ecosystem for any given place. As temperatures rise, climate zones are now shifting away from the equator quicker than Nature can keep up, although it’ll get there eventually. Maybe we help nature, rather than interfere when we bring in exotic plants that naturalise. Maybe those plants are the start of new ecologies that will adapt to the rapid changes that this climate emergency is bringing us. If plants do well, we need to understand how to enhance and build new ecologies with them. This is how we adapt, how we survive and how we rectify the damage we have done as a species; not by returning to some pristine “before” (which doesn’t exist) but by assisting Nature to heal and adapt. The Earth will do this all by itself, and has done so many times. It doesn’t mind if it takes thousands, or even hundreds of thousands of years to adapt. But we do; we can’t wait that long.
So horticulture needs to stop growing pansies in peat with unrecyclable plastic trays and start sorting out which plants really matter for our future; which ones contribute to new and existing ecologies, which ones are good for biomass, which ones contribute to soil health, which ones give us ecosystem services. We should not enhance one environment at the expense of another.
That’s a very-near future profession of trained eco-warriors, soil saviours, tree patriots and landscape lovers. It needs people who understand soil, who know how to design and use sensors, data and the internet of things, people who see what’s coming and how to mitigate and reverse negative effects, people who really know how to design and install green infrastructure and future automated robotic maintenance systems. Our landscapes can grow food in amongst all the beauty, with urban food forests. We need new knowledge built on old and we need passion, commitment. A wise government would fund this for the returns will be numerous.
This is the enlightenment, that out of dire stress and trouble, we could really learn how to value, connect with and protect this crazy, beautiful world within which we live. Or we can do nothing and watch it all go to hell. I know which I’ll be doing.
The emergence of the idea of resilient planting is a response to a number of different pressures which all have one underlying cause – climate change. Whatever the cause – and I’ll get on to that later – I see it as the most exciting change to the way we design our gardens and landscapes.
Last year we had one of the hottest summers ever recorded and it serves to heighten awareness of the vulnerability of some plants and garden styles to the increasingly erratic climate we are dealing with in the UK. We seem to swing from one extreme to the other, and this is only likely to get worse. I’ve witnessed a number of stressed plants in my own garden but feel relieved that most have thrived throughout the heat, without any watering on my part. this is down to soil, drainage, micro-climate and above all, plant choice.
Ballota pseudodictamnus, a Mediterranean sub-shrub with grey, felted leaves, loved by bees.
We garden on an alluvial coastal plain, and are fortunate to have a very free-draining soil overlying a clay substrate. It gives us fertile soil, great drainage and a moist sub-strata within the reach of most plants (many areas around us are of much heavier clay). A large section of our front area used to be a paddock with a rubble driveway and this now forms the basis of much of my dry garden. Some rubble was removed and topsoil added, but a lot of areas are still rubble-strewn, not unlike some rocky soils. The down side of all this is super-fertility and a soil filled with weed seeds, bindweed and couch. To be honest, I’d have preferred a poorer soil.
When thinking of resilient planting, we have to match our plant type to the environment; we also have to think, long-term, of how our environment might change in the coming years. This is not so important when dealing with short-lived plants such as herbs, sub-shrubs and perennials, but is super important when dealing with long-term structures, especially trees. This is doubly true when we look at the potentially disastrous effects of imported pests and diseases that we are having to content with. Climate change, especially milder winters, mean that exotic pests are happily making a home here and wreaking an unintentional devastation to trees such as our native ash and even oak.

No-one can say exactly which way our climate will go as the world hots up; we know we (in the UK) will always be maritime, because that can’t change, but as the Jet stream (wind currents) varies and the Gulf stream (water currents) weakens, we don’t really know what kind of climate we’ll end up with. We can only plan for extremes, and select our planting choices with that in mind. In this respect, the “new perennial” or “naturalistic” planting isn’t necessarily going to be the toughest choice as they come from a continental climate which generally have hot summers and very cold winters. Prairie plants tend to get out-competed here with our mild winters and grasses and forbs that can grow all year round, given mild conditions. The aforementioned fertility (at least in my garden’s case) also doesn’t help as wildflower meadows/prairies tend to have poor soil which helps keep the grasses from assuming dominance. During the heat-stressed weeks, I noticed that where I have perennials like Echinacea and Veronicastrum (in moister areas than the dry garden), they suffered from the lack of water. which resulted in the Veronacastrum flower spikes looking stunted. for more moisture-demanding planting, sub-surface irrigation using harvested rainwater might become a necessity.
To my mind though, if you need irrigation you’re working with the wrong plant-types, trying to grow plants that can’t naturally cope with the conditions that predominate. Save your water for the newly planted and the vegetable plot and for this, consider rainwater harvesting, rather than mains. When selecting plants, see what grows well, both of native and non-native origins and build adaptive micro-ecologies. Our climate is changing faster than the current ecosystems and ecologies can cope with and we need to do whatever we can to build new planting that is of maximum benefit to local wildlife, as well as ourselves.
It’s an exciting time to be a gardener, for there is no place now for the self-indulgence and nature-control-freakishness of the past. What there is a the possibility of co-creating new ecologies that adapt to changes, halt decline and make our local wildlife vibrant and healthy.
Along the way, we can create the most stunning of gardens!
Water in its purest form is the most simple of compounds – two atoms
of hydrogen to one of oxygen – yet it is possibly one of the least
understood “elements” on this planet. Strange, when it covers 70% of
the globe and our bodies are 70% water. We take it for granted now,
when once we considered it sacred. There is little appreciation of
water; we no longer walk to the well, there is no effort involved and
seemingly no end to its availability – except there is, but that’s not
what this article is about.
I want to try and inspire a deeper appreciation of this element
(not used to describe its chemical properties, for it is, as stated
above, a compound), we need to reconnect with it as the source of life
and spirit. I’ve worked with water for many years, building ponds and
experimenting with biofilters and natural cleansing methods. I work
intuitively, not scientifically and am the first to admit to large gaps
in my knowledge, with a path of learning ahead of me that still looks
impossibly steep! Yet the more you explore the qualities of water, the
more you get drawn in: the secret of life itself lies in there. To that
end, I have recently gone back to building new water features and
greywater systems myself, for there is no substitution for hands-on
experience and observation.
That water has properties “beyond the obvious” is a no-brainer –
you can observe many of these for yourself. Understanding what exactly
they are, how they are generated or destroyed, and just how far they go,
is another matter altogether. You cannot investigate water for long
without coming across the name of “Viktor Schauberger” an Austrian
forester who investigated/discovered/rediscovered the more mystical
properties of water during the first half of the 20th centaury.
So where do we begin, on a journey to a greater understanding of water? That’s difficult, but let’s start with what we can see: the way that water moves. Our mathematical minds tell us that the quickest way from A to B is in a straight line, but water doesn’t move like that, even when it could (in fact, nothing in nature does). Water moves in a never-ending series of spirals and vortices. Why? because that way water is energised; it generates or attracts minute electrical charges and controls it’s temperature, moving as close to the optimum of 4° C, when it is at its most dense (it expands either side of this point). This vortical movement causes the winding motion that we see in rivers once they reach the valley bottoms and plains, and the eddies and swirls you can plainly see in any moving body of water.
Vortical movement is centripetal, rather than centrifugal. It uses the force of implosion, rather than explosion. This form of movement gathers force and energy, rather than dissipating it outwards. Straight away this seems odd to us, for we are used to a science and technology based solely on the force of the centrifugal, explosive, dissipative; which inevitably must lead to loss and entropy. That Nature uses a different form of energy seems unreasonable to the scientific mind. It has been said that there is endless energy that can be captured from the movement of water (not from hydro-electric use) and if we could efficiently split water into oxygen and hydrogen by electrolysis then we could capture energy with water as the only emissions; but I do know that the way that water moves is strongly bound up with its health, and so the health of all life, and that is an area that interests me greatly.
Schauberger states that water tries to maintain itself at its greatest density of 4°C; then it has greatest energy and the water is at its most “enlivened” state. The problem with this is that it is difficult to measure or assess by conventional scientific means; this does not mean, however, that it is cannot be true. What we can say, however, is that water in its most natural state is the most healthy, and so at its best for both ourselves and the environment.
Water may also carries memory, which accounts for whether it is in an “enlivened” state or not. In homeopathy, a benign substance is diluted to the point where it is chemically nonexistent, but potentially very active, and this is based upon the latent memory of water. This is also true of pollutants, whose influence can still be there even once the source has been removed. Fortunately, water will self-heal if only allowed to move in its natural rhythms. The design of Flowforms is one response to this, allowing water to regain it’s own energizing movement, and other devices, such as spiralled copper coils and units containing pre-energised water are all said to effect and energise water that flows past them. I have no particular view about this, but then, I haven’t done any tests on such devises and of course, knowing how to measure potential results is always the problem. In pond ecosystems, health can be largely determined through observation and I prefer this approach, where the results of alteration can be seen in biological response.
There are a number of issues I have experimented with at times: enhancing the natural rhythms of water movement, enhancing biological activity in breaking down pollutants, and incorporating ornamental pond systems with purification of household greywater discharge, rainwater harvesting and garden irrigation. All these things require biological understanding and observation but to my mind, they most of all require an open mind and a sense of respect, an acknowledgement that water is in fact precious and scared.
I live in an area surrounded by intensive agriculture, which extracts groundwater to irrigate vast monocultures of salad crops. This is the worst kind of abuse of water, treating it as an inexhaustible utility, to pollute with herbicides, insecticides and fertiliser runoff. Mankind’s ignorance and lack of respect for the most fundamental and vital element on this planet can only lead to exhaustion, depletion and pollution on such a scale that the very existence of all life is put under threat. We need to look for the highest potential of life, not the lowest common denominator. Time to get critical in our thinking, and get connected back to deeper understandings.
The most exciting thing is that understanding water truly can reveal the secrets of life. Through appreciating this simplest, yet most profound element, I believe that humankind can come to a greater appreciation of himself, and his place in the Universe.
A problem, or an opportunity for a new landscape paradigm?
I was recently working on a tree project in Abu Dhabi when I came across a derelict site which intrigued me with it’s range of exotic self-seeded, non-native plants. The site was next to the Corniche and sandwiched between the Formal Park, my hotel and Capital Gardens. It struck me initially as the perfect basis of a xeriscape, as all the plants (mostly trees) were thriving without irrigation. On closer inspection and identification of the species involved, things got more complex and raised a lot of potentially conflicting thoughts and issues.
A natural Xeriscape
The site was clearly awaiting redevelopment and the plant invasion was opportunistic. Nothing that I could identify was native, yet all seemed happy there. When you see the list, you might understand why. Amongst the plastic and litter I identified:
Of those plants, the P. juliflora was the most robust and when you look at its reputation, that is of no surprise. It was of landscape scale, lush and greener than anything in the adjacent parks. It’s form, leaf, flowers and seeds are attractive from a landscape perspective. Yet this is undoubtedly the most controversial plant on this list – some would say alarming. A Native of arid zones in central and South America, this was, like so many others, introduced into the UAE in the 70’s as a forestry plant. Lauded as something of a super-crop tree, it is tenacious, vigorous, provides fuelwood and stock-feed in the form of abundant seeds. The latter, it turned out, were a problem in that they are spread by cattle and are extremely aggressive. Plants also regenerate rapidly from the roots when cut back and they reputedly produce biochemical inhibitors to suppress competition (allelopathy). With no natural competitors in the UAE and roots that can descend 50m in search of water, they out-compete native flora, even their cousin, Prosopis cineraria (ghaf tree).
Prosopis juliflora flowers
P. juliflora has a low, mounding habit, attractive from a landscape point of view.
Also on the site were a number of Banyan trees, Ficus benghalensis, which seemed to be growing happily. Another tough survivor, it should be borne in mind that the water table here is likely only a metre or so below ground, although it will have a high saline content.
Then there was Eucalyptus camaldulensis , another forestry/amenity introduction of the 70’s, also known and now generally avoided for its aggressive roots, yet here looking beautiful with its grey, lanceolate foliage. This was the tallest tree on site.
Eucalyptus camaldulensis , showing adult foliage
Of course, there was the ubiquitous Conocarpus lancifolius, widely planted still yet also recognised and a danger to any nearby drains, and on it’s way out in popular use. Except it does make such a good tall hedge, and it has a much nearer native origin, coming from Somalia, Djibouti and Yemen. I’m not sure that the UAE landscape industry is ready to ditch it just yet.
There was even a palm, Washingtonia robusta, self-seeded around the place. Much of it was to be found growing underneath the canopy of the P. juliflora, so that at least is not put off by any allelopathic biochemicals from the Prosopis.
I believe this legume is Sesbania sesban, more commonly seen with yellow flowers. Rose-ringed Parakeet
Inhabiting, or at least visiting the site, was a Rose-winged Parakeet. Another exotic invasive with beautiful form but aggressive tendencies; it seemed appropriate to the moment, somehow.
What does this mean for future landscapes and ecology?
From a conventional ecology point of view, these plants are all threats, and the threats probably outweigh their usefulness. So why am I even talking about this? Clearly, the move towards more naturalistic landscapes draws heavily on native species and would shun all of these species.
Except we have climate change.
Climate change is the elephant in the room, when it comes to ecology, in fact when it comes to sustainability generally and a livable planet overall. That we have already moved beyond vital tipping points is highly likely; that climate zones are moving away from the equator at a rate too fast for nature to adapt is a fact. Flora and even some fauna just can’t move regions that quickly. They will adapt, eventually; but those that are rare, specialist and struggle with change, will die. The tougher generalists will adapt and survive. Nature will build a new ecology to reflect the new reality, and it doesn’t mind if it takes a few thousand years to do so. Only we humans mind and so, if we are to survive, we must adapt our environments to fit the new reality. It is a sad fact that many cherished plants will eventually die out or move zones. In the UK, I dread losing our native oaks (I view these as our ghaf tree equivalent), yet we may get Mediterranean species to replace them, such as holm and cork oak.
If you are already positioned in the arid equatorial zones then you have precious few plants that will form your new ecologies and landscapes. Perhaps the plants I have described above will be UAE naturalized-natives in 100 years’ time and the ghaf and sidr may be gone, or diminished, or moved north. I hope not, but before we spend vast fortunes on eradication and control of non-natives, we should look to the future. These aggressive invaders may just form the landscape of our children; I know I’d rather live with a landscape, than none at all. If there is no landscape, there is no life. They may, in fact, be here to save us.
Once we grasp this fact, we can look at building new landscapes to suit our changing environments. I’ve written about this before and you can read the articles listed below. We must be vastly more holistic in our thinking in order to do this and broaden our horizons to understand the new future. Technology will help us to monitor, collect data and produce working strategies. Robotics and drones will help manage and control plant communities. Alongside that, we need a vastly better understanding of soils, microflora and fauna, for the bit of nature that we see is just, literally, the tip of the iceberg. The selection of tree and shrub species for adaptation is easy, we get this wrong when we don’t deal in whole context thinking eg. only thinking of forestry or ornamental benefits.
The challenge ahead is huge but in a weird way, exciting; it will challenge the human race to grow. There’s a whole new science to develop and we’d best get on with it.
According to Google, the site has been cleared some time in 2019:
This book represents a new wave of thinking about “natural” planting that has been emerging in recent years; actually it has been developing for the last thirty or more years but like all new things, they tend to follow an exponential growth curve. I’d say that right now we’re near the base of the steep upward bit with this one. Left unchecked, exponential growth tends to end in collapse but this idea deserves to stay the course. To do that it has to translate from a style into a design language and that’s what this book is really about.
This is a very US-centric book, unsurprising since Thomas Rainer is from Alabama and Claudia West, though of East German origin, lives in the US. I would have liked her influence to have given the book a more European feel; it would have been richer for it and more globally relevant.
The book has already been reviewed on TG by James Golden but although I’ve read this I’m not referring to it, save for one point. Needless to say, that review is also very US-centric; my purpose is to give a more UK/European viewpoint.
The thinking in this book is very design-led, in which the authors refer to landscape archetypes, which I think is very useful. However, they only select three – grasslands, wood and shrubland and forest. Given the vastness and variety of American climate types (which has just about everything), I’m surprised they didn’t mention desert landscapes, arid-mountainous or Mediterranean (as in Californian coastal regions); I suspect they have simply not worked with these climates, yet to omit them from a listing of archetypes is limiting. It is clear too, that their interest lies mostly in the grassland or prairie archetype.
There are many archetypes other than the three mentioned in this book. Desert near Dubai, UAE.
Referring back to the JG review, he wanted to add another archetype, Edges. I would argue that the wood and shrubland archetype is an edge, or rather a transition. Only in farmer’s fields do we have an edge as such. I would think of these archetypes as parts of a sine wave, one transitioning into another as climate and topography dictate. This sine wave also rolls around the globe over time, one archetype superseding another in any given place. Remember that the Sahara desert was woodland just 10,000 years ago, when we emerged from the last ice-age. This fits with the theory that there is no such thing as an ecological climax.
Another interesting thing to come out of this book is the idea of “designed plant communities”. You could say that any grouping of plants together is a designed community but the context they use of grouping plants by habitat-type rather than just their visual look is refreshing. This makes good sense, provided that such a designed grouping is appropriate within its wider environmental context. Taken to its logical extreme, however, you end up with native plants only.
What may be harder to work out is how much of this philosophy fits into a garden. Even the largest garden can’t fit in a whole wood, let alone a prairie, so of course, we must work by inference. This aspect of things is not really discussed in the book and most of the pictures are of large gardens in amazing settings; domains of the lucky few who we landscape designers occasionally get to work for. Yet for the majority of small garden owners, instruction for the adaptation of these principles is missing.
The Lurie Garden, Millennium Park, Chicago by Piet Oudolf exemplifies modern Naturalistic planting. This is large ribbons or drifts of plants rather than the species intermingling favoured in this book
The same garden in November; form is held in the stems and shapes of the seedheads but use of some woody plants might add more winter form?
I feel that the book only really looks at one archetype, that of New Perennial/Prairie style gardens and there is a big focus on this at the moment. I might compare this book with Oudolf & Kingsburys “Planting, a New Perspective”. That book, whilst not getting down to the archetypal design level, is more European in focus, so possibly a good companion read. Yet it too, mostly deals with perennial-based planting, as you would expect from these gents. The work of Nigel Dunnett and James Hitchmough comes to mind too. The fast-changing essence of many of the plant species used means that these perennial plantings are subject to rapid change, even degradation, over time as some of the most desirable and favourite species are so short-lived (Achillea and Echinacea for example).
I think the Wood and Shrubland archetype is the most likely to resonate with those seeking to create a garden, yet the ones of great importance to me, in a European and specifically coastal Southern England context, is that of the unmentioned Mediterranean or Arid-Mountainous archetypes. Whilst some areas of the Mediterranean clearly fit the Wood & Shrubland archetype (ie broadleaf and evergreen woodlands and Maquis), others such as Garigue, Salt Marshes and Rocky Shorelines, do not. I think this range and essence adds up to its own unique archetype. Arid-Mountainous too is quite distinct (although again with areas that fall into the realm of other archetypes), yet gives us wonderful, tough plants like Perovskia. The Dutch biologist Brian Kabbes has done much to inspire and educate us with his exploration of plants in Kyrgyzstan.

To me, one of the biggest drivers in creating naturalistic planting communities has always been about resilience. To my mind, planting should survive without irrigation, so low water-use plants are attractive. I can’t think of a single garden in the UK that couldn’t survive without irrigation, the desire to use pop-up sprinklers is ridiculous and surely industry-driven. Climate is changing now beyond speeds that Nature can shift plants and ecologies around the globe, so it is something we humans must do if we want a future landscape of any description (oh, and for our own survival). So we have to transmigrate landscapes from one continent to another to keep pace; yes, with all the risks that entails when introducing new species (and it would not be just plants we’d have to relocate). So learning about plant communities and how to build them is a vital skill which this book begins to explore, yet could have gone much further in instructing us on.
This coastal garden I designed in Southern UK loosely mimics the Mediterranean archetype, and uses a full range of grasses, perennials, sub-shrubs, herbs, shrubs and trees.
In the European context then, archetypes other than grassland/prairie might be more useful and translatable into a garden context. That this book has not covered these is not really surprising but it is a mistake to think that the new language of resilient/natural/sustainable landscapes is dominated by perennials and grasses. This aspect is possibly a trend within the underlying drive for a natural interpretation.
A European version of this book is needed, which could perhaps take it to the next level of design language development. In this respect, inspiration can be drawn from another book, “A Pattern Language” by Christopher Alexander, which although about architecture and space, is also about soul, spirit, context and community, realised through the use of a language of patterns. In a very real way, “Planting in a Post-Wild World” attempts to create an archetype-based design language and is a valuable contribution to that. We just need the language to be global, or to see this book as a regionalised attempt to cross boundaries and develop new thinking.
This is an important book and I recommend it; for all its limitations it shows the way to develop landscapes that are truly new and profound.
