|PULSATILLA BLOSSOMS TRY TO STEAL THE SHOW IN THE AMAZING ROCK GARDEN OF JACQUES AND ANDREA URDA THOMPSON IN YPSILANTI, MICHIGAN - PART OF THE NORTH AMERICAN ROCK GARDEN SOCIETY ANNUAL MEETING GARDEN TOUR|
I am still recovering from last weeks jam-packed trip out to Michigan where the North American Rock Garden Society held its annual meeting, hosted by the Great Lakes chapter. I've been to about 7 of these annual meetings and study weekends, and I can confidently say that this one succeeded spectacularly. As the current president of NARGS, I could easily be a little opinionated, but it would be no exaggeration to say that this particular event was flawless - perfect spring weather which encouraged some of the finest alpines and woodland plants into peak bloom just in time for a couple of hundred plant geeks, and I really don't need to say that after the winter we all survived, was nothing more than a miracle in itself!
|THE ROCK WORK IN JACQUES GARDEN WAS INSPIRATIONAL - SO NATURAL AND COMPLEMENTARY TO THE INTERESTING PLANT MATERIAL. A MOUNTAIN MEADOW AT LAKE-LEVEL!|
Being my first trip to Michigan, I was looking forward to driving out from New England, even though the drive would take two days and take me through much of Ontario, Canada. I felt that I needed the time to get my thoughts together for the board meeting which preceded the event, and to relax a bit ( yes, sometimes, driving can relax me, although it took the rental of a big, new Dodge Ram pick-up and a few hundred miles of white Trillium grandiflorum, the grandeur of Niagra Falls and the magnificent spring woodlands and fruit orchards of the Great Lakes region. I should mention that this event coincided with the spring migration of warblers and songbirds - the East Coast deciduous forest was alive and singing in so many ways - why would I ever want to fly in a cramped plane?

Mention the term 'Rock Garden' and most people will offer a different definition. Even amongst the most passionate of rock gardening enthusiasts - member of the NARGS - the North American Rock Garden Society or the AGS - the Alpine Garden Society in the UK, even within the chatty, active chat rooms and forums of the very active and passionate SRGC - the Scottish Rock Garden Club folks disagree on what the exact definition is, but one thing is for certain - rock gardening has less to do about rocks, as it does about the plants - for each personal definition does provide a hint to what rock gardening is today - a hobby or interest which demands more than some basic knowledge about plant life. The art and science of rock gardening errs more on the side of science, ecology and botany than it does the 'art' part of the equation.
Not that aesthetics aren't important to rock gardeners, far from it, but rock gardening is about as far away from landscape design or outdoor decoration as a garden can get. In a nut shell, it's more like recreating nature - think: habitat creation. Many rock gardens are like tiny zoo's for plants. Want to raise a rare, high elevation saxifrage from the Alps? Then you will need to recreate the alpine conditions as best you can right in your own back yard - right down to the perfect drainage, soil pH and rocky outcroppings or screes where the specific genus once grew in nature. It's a bit like creating a living diorama from a natural history museum - perhaps right in a small trough sitting on your deck, which is kind-of cool once you start thinking about it, right?
|PURISTS IN THE ROCK GARDEN SOCIETIES STILL ENJOY ATTEMPTING TO GROW THE MOST CHALLENGING OF PLANTS - HIGH ELEVATION ALPINES SUCH AS THIS SAXIFRAGE SPECIES I SHOT IN ONE OF MY TROUGHS, BUT ROCK GARDENING TODAY CAN MEAN SO MUCH MORE.|
Although many rock gardeners focus strictly on alpine plants in the UK, in the US the boundaries blur between interests - ferns, woodland plants, bulbs, shrubs, cacti and succulents and true, high-elevation alpines. So even though the first rock garden movement in the 1910's, kick-started by a British plantsman and explorer Reginald Farrer - the 'Father of Rock Gardening' -as he he ignited the trend back in the Victorian era and it grew into a specialist favorite throughout the first half of the 20th century. Near the end of the 20th century, the trend started to wane, to evolve into what rock garden is today - more about interesting plants and the people who crave them, than anything else. Some of use still raise proper rock gardens in the English style, others, do it with a twist, raising plants in troughs, raised beds or pots.
That all said, 'Rock Gardening' expland into many tangential specialist groups including the Penstemon Society, the Primrose Society and many other highly specialized groups based around a single genus. Then, there is California and the water shortage, where rock gardening may mean a water-wise gravel or sand garden. Similarly, in Arizona, it may mean a cactus garden or a Steppe garden, or in Colorado and Utah a mixture of all three. In the North East, it may mean getting rid of your lawn and introducing native plants.
There is still an identity issue here to those trying to wrap their arms around what rock gardening actuall is, but there is one thing clear to all rock gardeners - a rock garden is not simply a garden of rocks. It's about creating an environment or a habitat where these plants can grow, as most will sulk in a regular garden. This may mean fast drainage, protection from winter wet, or sand beds, gravel mulches or tiny crevice gardens of clay.
Even nurseries and garden centers are confused, often clumping together various low-growing or dwarf plants in areas and labeling them as 'rock garden' plants. There are only a handful of true alpine plant nurseries in North America, but as the term broadens to include woodland and shrubs and grasses, you can begin to see that a rock garden enthusiast could find a suitable rock garden plant in many aisles of a nursery, but the purist would most likely need to either join a local club, or order plants from a specialist nursery as few garden centers carry any rock plant beyond a sempervivum or a dwarf campanula.
In many ways, the North American Rock Garden Society is stuck with a very unfortunate name. It may have been appropriate in 1930, but today, it can be misleading. First, the idea of a 'society' is limiting and off-putting to some, then there are the words North and American - it used to be called the American Rock Garden Society, but once again, Canada is left to fend for itself, so the name was changed. Even so, North America is limiting as well, especially as NARGS is a global society now. The word 'Rock' has many believing that rocks are essential to rock gardens ( and in many, they are), but as you can see here - rocks are only part of the story. What about bulbs, ephemerals, woodland plants, wildflowers, prairie grasses or ferns and mosses?
Clearly, this is simply a PR and identity issue more than anything else. We should be smart enough to be able to overcome such issues, but changing names of large organizations is challenging, and although acronyms seem to only make the matter worse (NARGS…really?), the future of these groups weighs more on the members and what they believe in more than it does what they are 'in to'. It's safe to say that NARGS, AGS and SRGC attracts the most intellectual of the plant people, sure, but it also attracts those who are curious, smart, adventurous and who love learning more about plants.
|A GROUP OF NARGS MEMBERS MEET ON A SATURDAY FOR A BOTANIZING HIKE. USUALLY THERE ARE A COUPLE OF INFORMED LEADERS, AND EVERYONE ELSE TAKES NOTES AND INSPIRATION. THESE ARE ALWAYS A GREAT TIME FOR NOVICES AND EXPERTS ALIKE.|
Of all the benefits that are worthy with these groups, by far, the best part of membership are the sed exchanges. Annually, each of these clubs offered members a long, long list of fresh seed - seeds available from no where else - forget about saving heirloom tomatoes - what about an endangered plant from Brazil who's habitat has been destroyed, thought to be extinct? I want to save THAT seed. Not a bean that I am saving because of some crazy, unfounded GMO fear. Make a difference in the world.

Attend any local or even the national annual meeting ( in two weeks???) and you will find a cheerful, friendly group of plant enthusiasts who welcome both newbies and experts. You just need to be curious and open about learning new things. Friends tell me that attending meetings is a little bit of boy scout meets a college lecture.
|THE BRITISH SOCIETIES ARE VERY SOPHISTICATED ABOUT HOW AND WHAT ALPINES TO GROW, AND I TRY OCCASIONALLY TO IMITATE THEM IN THIS ALPINE HOUSE COLLECTION OF POTTED, TRUE ALPINES AND SMALL BULBS. NOT FOR EVERYONE, BUT I REALLY ENJOYED THE CHALLENGE.|
My love for rock gardening and alpine plants started early in life, when I was a gardener at a small estate here in my home town which happened to have an extensive rock garden, tufa rock walls and an important collection of true rock plants. I just never took it all very seriously until I was much older, when about 20 years ago I started visiting some of the British sites - the Alpine Garden Society in the UK , in particular, as well as the Scottish Rock Garden Club. Both have deep sites where they share many photos of their shows which happen it seems, every other week. No one can grow alpines in pots as well as those in the UK can, but believe me, I try. Just check out their show reports here - the Scottish ROck Garden Club imges are here. Ian Young's bulb log was the inspiration for my blog, he and his wife Margaret are both active members of the Scottish club, you just have to visit his extensive collection of images on his bulb log here. It is insane!
|THE PLANT SHOWS OF ROCK GARDEN PLANTS IN THE UK ARE SPECTACULAR. MOST GROWERS RAISE THEIR ALPINE IN POTS AND IN ALPINE HOUSES, WHICH ARE ESSENTIALLY COLD GREENHOUSES. ALPINE HOUSES ARE DIFFICULT TO KEEP HERE IN THE US, BUT MANY OF US TRY.|
I kind-of knew that I could not raise such plants here in the US, but I have tried - unfortunately, our climate doesn't' cooperate in most of the US (unless one lives in Alaska or the North West), but I tried, and continue to try to raise alpine-type plants in pots and containers. I brought a few of these to my first NARGS meeting where I quietly entered them into a show - basically, a folding table near a window in an all-purpose room our local chapter rented at a state park. Most meetings occur monthly, and some include an opportunity for 'show and tell', where members can bring in a pot or even a cutting of a precious plant, and members talk about it - sharing how they grew it. There is usually coffee and treats, and then a presentation of some sort, usually a guest speaker. A great way to spend a Saturday.
It was at this first meeting when I realized that although I knew so little about these plants, that everyone was taking notes, laughing, sharing stories about how they killed something, or triumphed with it. There was a plant auction ( it was spring) and members brought in plants that they grew or divided at home ( a note about this - NARGS members run the full gamut, from novice to expert - and it's these experts, which most chapters have in one way or another, that make membership so special - in this way, NARGS is not unlike an elite country club.
At this first meeting, I met and became friends with Darrelll Probst, the then epimedium expert who offered up few flats of rare plants that he raised from seed that he collected on expeditions to China with Dan Hinkley. These were amazing, to say the least - I mean, podophyllum that were just too precious or rare to sell to commercial nurseries like Plant Delights because he only had ten of them - each plant made me want to empty my bank account. " This white dwarf Iris came from my last expedition to China, we are not sure about the taxonomy, the species may be new to science, it's only 8 inches high, and covered itself with white Iris blossoms early in the year, super hardy and it makes a huge mound - no one has it yet, so I'll start the bidding off at $5 - any takers?). Crazy.
At the same meeting, I met chapter members allium expert Mark McDonough, bulb expert Russell Stafford of Odyssey Bulbs and the speaker who spoke on water-wise sand beds. I bought a beautiful hyper-tufa trough and a few flats of woodland plants, bulbs and alpines, a small Daphne shrub that a member started from seed ( a species which was hard to find) and I bought a tall stack of old journals that another member was selling. Throw in a few books from the chapter library that would be lucky to every show up on Amazon, and I was hooked.
I couldn't wait for the next meeting - but I had to wait for an entire month! How could I ever survive?
NARGS is like that. Nothing at all like what my mother said rock gardening was about - rocks, placed in a garden. Ha.
Don't get me wrong, there are plenty of rocks in rack gardens - in particular, tufa rock, a porous limestone rock treasured by rock gardeners for true alpines, as they can root directly into the rock, but it is difficult to come by, and if you do, it is expensive. Hyper-tufa is a concrete mix, I think you've all seen it - people use it to make troughs or bowls in which to plant alpine plants. You may remember it being used in some classic Martha Stewart Living TV episodes, or from a few DIY craft blogs. If done right, it can look very much like rock, and it is the preferred method for creating troughs, a very specific type of alpine garden where high elevation plants are raised in carefully constructed troughs which mimic the stone sinks early rock garden enthusiasts used in England, but if done poorly, it could look like dinosaur poop.

Regardless of how you define rock gardening or what a rock garden is, the art and science of it makes sense, as explained in a nice post on the NPR blog this week - where the author has shared some interesting thoughts about how relevant rock gardening can be today.

So in an effort to promote rock gardening or alpine gardens, I am offering two precious copies of the latest journal of NARGS to two randomly selected readers who leave comments on this post - how great is that? In this issue, you will see articles on plants from expeditions to Afghanistan, to China, and Patagonia, but mostly, I hope that you will see that rock gardening is more about discovering the wonder of some of the most special plants in the world, be they endangered or threatened, curious or odd, or simply rare and undiscovered.

This weekend I am attending the Annual Meeting of the North American Rock Garden Society being held in Santa Fe, New Mexico. Having never been to either Santa Fe or even New Mexico for that matter, I discovering why so many artists and creative people love this city. It's unique Pueblo style architecture with adobe brick and stucco is amazing, not to mention the food, the people, the weather and the chili's.
As some of you already know, I am so proud to have been elected as the new president of NARGS this weekend, and I am so excited to have been both nominated and elected into this two year term with such a respected plant group as the North American Rock Garden Society. In many ways, I feel so un qualified as there are many expert gardeners more qualified than I, as the membership includes some of of the finest botanists and plant enthusiasts of any plant group, but I understand the mission at hand - revitalizing, re-energizing and perhaps reinventing a group of smart, passionate and dedicated plant people and leading the way for a brighter future. Something many plant societies will need to address in the coming years. I cannot make many big promises, but I can and will tell the membership that I will do my very best to inspire and bring a positive energy to the group.
The adobe architecture in and around Santa Fe keeps authentic, much like parts of New England.
I am very busy here, as meetings and hikes continue every day, but I thought that I might share some images - with very little text. Enjoy!

The Alpine Rock Garden at the Denver Botanic Gardens is world-renowned for its diversity and collections of high-elevation alpine plants, and western US native plants, steppe plants and succulents. One of the largest rock gardens in the United States, I saved this garden for a different day, as it deserved a more focused visit. Rock gardens can be controversial - at least properly defining them when garden geeks get together. Even today, many gardeners cannot agree on where they should be gardens filled with rocks, or gardens constructed to house true rock plants or alpine plants. The Alpine Rock Garden at the DBG is a little of both - but it is clearly inspired by the great European rock or alpine gardens from the turn of the century. This garden houses many plants native to the prairie and steppe areas of the great American south west. Purists may grumble, expecting to see sweeps of gentians and pulsatilla such as those seen at Kew or the Montreal Botanic Gardens, but the DBG garden is unique in the world of alpine gardens, and it is often listed as one of the great three ( Kew, Edinburgh and Denver) Rock Gardens maintained today. It alone is worth a visit while in the Denver area.

As many of you know, I adore alpine plants, and some of my favorites are the Primroses ( Primula) which grow near the highest peaks of the world. Here are a few of the highest elevation primula, which happen to be our first blooming primula of the season - much more to come. These are being grown in stone troughs, and in crevice gardens, where the tight spaces allow the primula's roots to grow deep in search of water. Primula allionii blooms very early in the Alps in France and north western Italy, where it grows on steep cliffs where it is protected. Hard to reach, these tiny primroses can grow in the tightest of crevices. There are many named forms and selections of P. allionii, and in England, a plant grown in a cold alpine house with care, can be covered completely with flowers so thickly, that you cannot see the foliage ( see one here). In North America, we are lucky if we get 5 or 6 flowers, which are still beautiful, especially this early in the year.

There are many named selections of Silver Sax's as well as many species but they are not easy to find. One must either mail order them from a handful of alpine plant nurseries ( mine are from Wrightman Alpines) or, one can start them from cuttings that you can take from a friends' plant. I plant my cutting in holes that are drilled into Tufa rock, a limestone rock which is porous, and also hard to find, but worth searching for at alpine nurseries, for it is the only rock that these planted will grow in. You might try these alpined in soil or a gravelly mix, but between you and me, there is really only one way to grow the giant specimens like these, and that is to root your own plants directly into Tufa rock. Once established, they are rather care free.
A silver saxifraga growing in a trough. I still need to clean up the troughs, use tweezers to remove pine and spruce needles, and then spread a new layer of granite chips, but beyond that, there is little care.
This slow to establish beautiful and rarely seen member of the Buttercup Family is perhaps only occasionally seen in plant collector's gardens, but that's a shame, since once established ( it is only difficult to transplant), it can live a long time. As one collector stated, "Adonis are easy to grow, but difficult to find", this is because they plants resist domestication. If one is able to obtain a plant that was carefully divided while dormant, and gets it planted immediately, then one must leave it alone and let it grow undisturbed. If new plants are desired, even seedling resist any disturbance, so although not difficult to raise from ones own fresh seed, success if better if the plant is allowed to drop its own seed into the soil, and young plants moved extremely carefully in the following years.
This is our second year with this division so it is still just settling in, but once established, I expect a dozen or so of these bright cheery yellow buttercuppy flowers very early in the spring, perhaps even with some snow on the ground. It is perhaps the most desired plant by many plant enthusiasts the Ranunculaceae family and its leaves and flowers look very much like the genus Anemone, and not buttercups, which is a good thing. In the garden, the overall appearance in not very buttercup-like at all, and more like Eranthis, the winter Aconite, if anything.
Adonis vernalis is native to Europe, whereas the more commonly seen, if one can say that about Adonis, is the Asian species, Adonis amurensis, which is highly collectible in Japan where many forms have been introduced. Our Adonis vernalis was started from seed collected in the Czech Republic started by Harvey Wrightman's Nursery, where he shared a few plants with us. Harvey WrightmanMostly this is a plant shared by collectors, but look for it, for one could call this the Peony of Ranunculus'. The other species which is sometimes more available is the Asian form, Adonis amurensis. Try ordering it from Asiatica.com.
When I planted the dormant potted division last autumn, I didn't realize that I planted in near a dormant Corydalis bulb clump, so this late summer, I will relocate the Corydalis solida, not the Adonis.
Many non gardeners may think that the winter garden offers little in the way of interest or display. But many plants offer year-round interest, and walking to the greenhouse today, I noticed how pretty my many troughs of Saxifrages look in the winter, with their lime encrusted foliage, and their silvery leaves that are as hard as rock. I am amazed at how sturdy these high mountain plants are, and each and every year, as I add and collect more, their diversity and beauty stops me, and I am reminded of why I love unusual plants so much. You are unlikely to find Saxifrages at your local garden center, or at a big hardware store garden shop. But you can find them online at a few alpine plant nurseries. Saxifrages are worth searching out, for these are one of those things like the finest cookware is to a cook, or a fine imported tool, that get's better with age. Saxifrages seem to say " Hey, you are a serious gardener, and you undoubtedly know what you are doing". Well, if you are like me, you may like things that 'say' that.
Not all Saxifrages are alpine plants, for some are downright huge, and tropical. But it is the alpine species that are so collectable and cherished by rock gardeners, and alpine plant enthusiasts. Saxifrages that are alpines are tiny, lime encrusted plants, and often for dense, hard mounds that alpine gardeners lovingly call buns. The dense buns are hard, and tight, they way we like buns. In the wild, they cling to rocks and cliffs on the highest peaks above the clouds, in in the mist, but they are sturdy and strong, in fact, they are designed for snow and harsh, misty conditions, but, conditions that are exact. T
So why don't you see them everywhere? Well, the reason you don't see them that first, they are considered challenging to grow, and, they are not suited to mass productions for retail garden centers. Plus, they bloom in the late winter, or very early spring. When you see a trendy trough garden workshop on TV or on a make over show, what the host reccomends planting is often hens and chicks, sempervivums, and sedum's. These are incredibly foolproof we all know, but hardly something you can show off or impress with. I like semps, but sempervivums are best left to the casual gardener, for although pretty, they are rather unexciting, and boring, a toddler can grow them.
Saxifrages require an informed mind, and an experienced alpinist to master. ( They don't, but everyone still thinks so, even experienced rock gardeners ( read on) Or, so, they did, for today, I feel most anyone can 'master' growing this once difficult and fussy alpines, but don't share my secret with too many people! Just quietly order some, and pot up a trough, and leave it alone. Then, sit back and watch the most experiences horticultural snob's eye's pop out when they see your trough of these precious, high alpines, all dense and bun like, and you can exclaim...."oh those?, They're so easy, I really don't pay much attention to them". And, here's how...
Here is my big secret - although they are notoriously fussy ( I don't think so, though), they are easy if purchased from one retailer online Harvey Wrightman, for he not only has a premiere collection from the finest sources in Eastern Europe where the best come from ( the Czech's are crazy about Sax's), Check out their Rock Garden site if you want to see some incredible Sax's. But the reason you must get your plants from Harvey is because he grows his Saxifrages in blocks of Tufa rock, which makes them incredibly fool proof.
Look, you can still kill them, but think about this: I lost hundreds of Saxifrages until I bought Harvey's stone grown plants. I have lost none in over 4 years, and although costly, they have grown into large, if not huge, specimens in my troughs. And.....I rarely do anything to them. They get snowed on, rained on, full sun, and rarely watered, they are exposed to all of our New England elements. So, if you've ever wanted a winter garden, or a container that looked as good on the New Year, as it does in March, and in August, then consider planting a trough of Saxifrages, and maybe next year, you too can have a container of stars on your terrace or deck.
The only thing they dislike is winter moisture, and summer humidity. Many of these Saxifrages offer pretty flowers early in the year, perhaps late February or March here in New England, and often are the first sign of spring in our garden, long before the crocus and spring bulbs even think of emerging. Easy to grow in Hyper-tufa troughs, the sort Martha Stewart has shown being made out of concrete and peat, or grown in a frost proof stoneware container, Saxifrages are fun to collect, for there are countless hybrids and species.
