Mecca: Wisley

Wisley's Crevice Garden is Big.   
(click to see its full breadth)

42 tons.

In January, I visited one of the largest crevice gardens in the world, one of the most important, and famous.

The RHS (Royal Horticultural Society) Wisley is not far outside of London, pretty close to Heathrow International Airport.

The crevice garden, built by RHS staff (headed by the kind Paul Cumbleton at the time) and led by Zdeněk Zvolánekwas executed in 2010.  It is based on sand, which is entirely invisible.
For nitty-gritty details, see the diary of its construction.

Pictures I had seen of the garden didn't move me much, but perhaps that is the artist blood in me, because visiting it was different.  To be in the same space as this installation is truly, unequivocally impossible to convey in a picture.   Standing next to it was dizzying.  Know that pictures will never serve, that this is a fine art peice that one must be near to experience.  Would you judge Old Faithful by it's mugshot?

The sense of space is staggering.  It is very much a small mountain-range enclosed by hedges and within the auspices of an alpine house.  It's a pet mountain range, if you will.  The dramatic verticality of the stone is so catching, no passerby, no matter how disconnected from nature nor the physical world, could walk by without being taken aback.




The rest of Wisley is a special treat; a jewel in the crown, not to be ignored. Even in January.

The Alpine houses are institutions to themselves, requiring the toil of a fine staff to maintain a stock of plants outside of the exhibit which outweighs what is publicly seen at any given time.  It is so important to honour the appreciation of the relationship between gardeners (or caretakers, curators.) and the exhibit (plants, collections).  This is not immediately obvious to non-gardeners, but plant lovers are the heart and soul of such places.  They know the balance between nerdy botanical curiosity and general appeal, because the not only deal with the public who patently remind them of this truth every day, but live with this balance in themselves.  The truth is that both are critical.  Both are essential.  A stunning masse of fiery orange annuals  may be a hook which lures a human to a deeper love-affair with plants, but there must also be a substance and a culture of sophistication for the world of horticulture in an exhibit somewhere else.  Wisley's Alpine Department is one of those places, and their front-line exhibit is still stunning even if it is not a sugary bed of bright daisies.

There is a trend wold-wide in botanical gardens for sex-appeal, shock-and-awe, and bottom-line-worshipping marketing-efficacy fever.  As a business owner, I am deeply and profoundly aware of the importance of the bottom line (since it is directly tied to being able to eat or not!), however, the culture of "public impression," "public face," "public perception," and image,  driven by a campagn to make better numbers (visitors, income, etc) is starting to dominate like white blood cells attacking their own body.

The quality, the work, the legacy, of botanical institutions everywhere, is suffering.
All this marketing, business-headed priorities, perhaps fueled by the birth of the information age, is a fertile environment for performance-based and purpose-forgetting corporate style.  Worst yet, it sustains itself and progresses forward, since it feasts on numbers and is mathematically justifiable.  But that does not make it right.  

Botanical sophistication is being censored.
Perhaps Mark Twain's quote on censorship will serve:
"Censorship is telling a man he can't have a steak just because a baby can't chew it.'

Shall Botanic Gardens stop planting Lewisia because most visitors don't know what one is?
Many are.

Britain's botanical institutions have a longer and deeper history of honouring "collections" (or, the variety and documentation of all the plants they grow and show) than other gardens around the world, whose main goal is an attractive public space which uses plants as the material to get it done.  This balance must be reckoned.

 My greatest thanks to Mr. Paul Cumbleton, who is the retired ex Alpine Head at Wisley.  He took the time out of his day to shoehorn me into the garden in my limited time in London.   I regret having so little time to spend with this humble yet deeply effective man.



An institution which prioritises education and "collections" has plant signs...

A study of the plants in it betray that all sorts of fine things are happier there which were not possible in other areas, and that a small set of plants are not happy, including a fir or two, as I recall, perhaps because they want rich, humusy soils and cannot get their nutrients from the minerals in sand.  But look at the rest that do! 

And even the Royal  Wisley had not even been able to fill every crack, every nook and cranny!

APEX: the last days


My calculations showed we'd need about 1000 plants for them to even be visible in the garden. It's a big space, so I budgeted for that. Donated plants brought the total aim to 1200 plants.  Soon, I'll have a final count.

The big news was the help.  Just about the time I should have been panicking about being able to get all those plants in the ground, friends came out of the woodwork (and even faraway places) to plant.  Having been quite occupied with the logistics of acquiring such a large number of exotic plants from all over the place, they totally saved the day. Truly, it would have been a disaster without their deus-ex-machina efforts.

Margie Frey, left, former horticulturist/head gardener of the Western Colorado Botanic (where she did a heck of a job making more improvements with plants than anyone had in recent memory, in my opinion) came to plant.





Creating the system for recording where everything was planted was Kevin Pykkonen, of Boulder, who has been present and involved with every part of this thing.  His keen passion for the fanciest plants made him a specialist at figuring a few things out.

Gordon and Stephanie surprised me by coming all the way from Colorado Springs. They bravely faced the most barrel-cactus intensive bed.  Gordon did it with sandals.


Van will now demonstrate the right way to plant a cactus.  With salad tongs. A trick courtesy of the Chinle Cactus Club in Grand Junction, Colorado.
He'll even translate into Japanese.

The right depth can be maintained with the tongs while one backfills the hole with the other hand Yep, we even bare-rooted the cacti.  

Proof I actually did some planting myself,

Marla of Roots Medicine Gardens, threatening to show us what a little agave medicine is like.
Marla is responsible for compiling the database of plants which will one day be online for public access.

I really do like the way radially-arranged Agaves look in the matrix of a crevice.



Stomatium sp, from the soon-to-be-closed Timberline Gardens opens in the late afternoon, just as the nearby 'Gold Nugget Delosperma basuticum is closing.  It's a fun handoff.  There are varied opinions, including fruit, as to what the Stomatium ("Hardy Tiger Jaws") flowers smell like.

Deb came down from Boulder several times to get sandy hands. She's been madly engaged with this whole crevice garden style thing.  I'm jealous because I think she was having more fun that I.

Ken was a stalwart presence for the planting.  He made lots of friends by bringing snacks.

For lack of better material: your quiz

There is a nice stack of fun new information to share on the blog, but stacks of discipline do not abound {needed to research and compose it}.

In the interim, here is an appeal for identification.

This Fumariaceae member appeared out of recycled potting mix, which has subsumed many many year's worth of ungerminated trays sown with European seed exchanges.  These pictures are not sufficient for me to properly identify it. (One needs to see what the tuber looks like, the sexy bits on the inside, and basal leaves/scales.)  It has grown quite strongly, re-bloomed, and even survived drought in a pot before it went into the woodland spot in the garden.


Any ideas?  I'm 90% sure it's a corydalis.
Thanks.

To Friends in Santa Fe

I'll be giving a talk in Santa Fe in two weeks, and I wanted to post this in case anyone dying of winter stir-crazies nearby wants to come out and join us in warm talking and dreaming about gardening (mostly Rock Gardening) to melt away the winter blues:

Bee sex-dolls.

Thanks to a comment in a research article within the SIGNA newsletter (Species Iris Group of North America), I learned this morning that one of my holy grail plants recently earned a devious title.

Orchids have been the long-known tricksters which, through appearance and smell, convince bees to try the hanky-panky with them, of the genus Ophrys, one species of Seraphias.  



Warning: the following link contains apian* pornography.
Once you've gotten over the fact that you have just watched a video online of a bee dry-humping a flower, note gracefully and with wonder how the orchid actually affixes a fancy gluepad-strut-and-pollen-bag device to the back of the bee. Fantastic, eh?

But there is one plant which is clever enough that is not an orchid which some of us know and love already- a certain rare bearded iris, in fact- Iris paradoxa.(1)  I am tickled to learn this little raunchy fact about one of my favourite plants.

 Iris paradoxa


* bee-related

Lastly, know this blog will swing back into its less-seen theme of travel for a time this winter.

A little less salt, please: Survivors in a salty unwatered garden

notes on Xeric Plants for {very} Salty Soil:


My very first unwatered professional landscape is a business:  Woodstove Warehouse, at 946 S. 7th Street in Grand Junction, CO.

And if I'm allowed to critique my own design, I could stand to have used multiples of one kind of plant in areas, and near eachother to prevent the plant-space-plant-space, dot-dot-dot effect I so abhore.  I've since added a few plants to that end.


But the secret is that it's salty. The soil is incredibly rich in some form(s) of salts, which I've admittedly not tested.  Especially after long periods of dry weather, a white incrustation even forms on the soil surface jsut visible between peagravel stones.  Around here, it's called "alkali" and is famously visible from your car, covering entire fields, or even miles, in white, where few if any plants, including weeds, will grow.

After rains, it is invisible and plants which suffered from it, like the Desert 4'o'clock (Mirabilis multiflora) above will grow normally for a while, then return to suffering from classic salt-burn symptoms.


True to name, Saltbrush (Atriplex confertifolia) from Chelsea Nursery
has done great in even the worst spot.

Then there are the intermediate sufferers, like the Desert Evening Primrose (Oenothera caespitosa) who opened a can of Pheonix-style:  It was planted, bloomed, and completely killed when the salt rose up, but upon the salt being pushed down by the monsoons, germinated from seed only to bloom again!

I trialed a list (which will be documented here) of plants I put in the "flowery flower" category to provide colour among the different shrubs, and most of them died, exept this, Prairie Zinnia (Zinnia grandiflora), who has not even shown a modicum of distress.

Yucca harrimaniae is doing a funny thing- and this is a classic salt response.  The tips of leaves, epecially old ones, dramatically die- the salt in the plant's body is accumulated there and that part of the leaf is metabolically scuttled, if you will, to rid the plant of some of that salt in favour of preserving newer leaves. Or so the scientists say.



For the record, Ephedra viridis (Green mormon-tea) is zipping along ignoring all traffic signals- this one has grown several feet this year alone. (Amen to bareroot planting, amen.)

Perhaps it's the position in-between rocks, but the Grand Canyon Agave utahensis var. kaibabensis  is growing stronger here than in my home garden.

Prickly Pears (like this Potato Cactus, Opuntia fragilis var. denuda) seem only a little slowed-down, and there is a faint yellow mottling, which I cannot conclusively attribute to salt, but that is my guess.

A heroic Joshuatree has pushed through a near-death experience. (Yucca brevifolia)

Some Chollas suffered a little in the beginning, but they seem to be steady now, enough to send roots 9 feet away when they are under 3 feet tall themselves.  To say that Cacti are shallow or small-rooted is a gross generalisation!

Now, the meat. The lists of plants.  This is an empirical but non-scientific record of this property, which is not authoritative, but hopefully useful:

Just dandy with salt:
Atriplex confertifolia
Atriplex cana
Atriplex gairdneri
Opuntia phaecantha
Opuntia polyacantha v. schweriniana
Opuntia fragilis v. denuda
Ephedra viridis
Ephedra minima
Ephedra minuta
Echinocereus trglochidiatus f. inermis
Echinocereus triglochidiatus
Yucca baccata (Funny when others behave with complaint)
Fallugia paradoxa (this also tolerates being so wet it's underwater occasioanlly, then bone-dry again)
Chrysothamnus/Ericameria nauseosa v. nauseosa (Baby Rabbitbrush)
Chrysothamnus/Ericameria nauseosa (this grows wild around the corner)
Sporobolus cryptandra (must be included, having recently been posted about)

Suffered, but didn't necessarily die:
Yucca harrimaniae
Yucca brevifolia
Onobrychis viciifolia
Oenothera caespitosa- plants die, but seed grows during less-salty windows.
Cylindropuntia kleinii
Cylindropuntia leptocaulis
Cylindropuntia aff. whipplei (Silver Spine/Snow Leopard)
Amelanchier utahensis
Sphaeralcea grossularioides (some plants died, one thrived; borderline plant. Wierd, too, because it grows near saline soils in nature)
Sedum telphinum 'Autumn Joy' (Client pick; I never would have guessed it would work)
Tribulus terrestris (I included this weed in the list for fun and reference.  Its leaves yellow, but unfortunately, Goathead/Puncturevine {or little-devil-of-the-earth, scientifically} doesn't die!

Plants on the property, but I'm not sure their feelings about salt:

Opuntia 'Dark Knight'
Cupressus arizonica
Perovskia atriplicifolia
Grusonia clavata
Agave parryi
Agave kaibabensis
Escobaria sneedii var. leei

Forget it/ Epic Fail:
Artemisia tridentata (no kidding, sagebrush can't take it)
Stanleya pinnata (so shocking, I tried 3 times!)
Astragalus mollissimus (more shock)
Castilleja integra
Hymenoxys acaulis
Calylophus fendleri (crispy critters)
Eriogonum corymbosum
Ephedra torreyana (this is wierd, since this is the species which naturally grows closest to "alkali."
Mirabilis multiflora (one plant is barely alive from many plants dead)
Nolina microcarpa (I'm willing to kill this again just to make sure)

Upon writing this, I realise I need to try Berlandiera and Penstemon. How dare I forget them in the great procession of death and suffering?
