In search of lost time: Sani Pass almost 20 years ago....

Sani Pass, January 1994
They have sat there for decades now, in the depths of my closet. A metal box full of pictures I took in 1994 on my first trip to South Africa. A volunteer at Denver Botanic Gardens--Ann Frazier--has begun to scan these transparencies--most of which were shot at the wrong ASA, but through the magic of digital enhancement we can almost recover the original color.  I gaze at these pictures that she accumulates every week with an enormous sense of nostalgia and gratitude. That was my first trip to South Africa. Although I have been up Sani Pass at different seasons and other years, that was my initial exposure to one of the floral wonders of the world. The Delosperma in the picture above is a mystery to me. Something in the lavisiae/obtusum complex no doubt. The Helichrysum in undoubtedly H. confertum--one of the greatest rock garden plants not yet in cultivation. Just look at those big fluffy clouds. Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhh! (That's a big heartfelt sigh)...


Koos Roux on the summit
 I have mourned Koos recently, and will not repeat my lament--but what a bittersweet pleasure it is to see this picture of him back then. My Cicerone and boon companion.

Senecio seminiveus
 One doesn't imagine senecios growing next to water: this is actually a wonderful rock garden plant and the foliage can be quite silvery as well as this matte green...


Mystery Helichrysum sp.
 I would never have remembered this amazing selaginoid Helichrysum which I've never seen since--wouldn't that be a fun plant for a rock garden?

Sani pass from Sani top
 Looking at those bald hills from a distance, who would dream that they harbor literally thousands of kinds of spectacular plants?

An unknown species of Lizard
My garden mentor, Paul Maslin, was a great herpetologist--so I naturally try and take pictures of lizards whenever I can. I also captured some mysterious red flowered composite (or at least I think it's a composite)--South Africa is like that. Something mysterious wherever you look...

And so it goes--I have not nibbled on a Madeleine, as had the protagonist of "A la recherche du Temps perdu", but seeing digitized and "cleaned up" versions of these old images has just as heady and emotional an impact on me. What a treat to have these nuggets of one's past reappear like magic! Thank you Ann!

A Masterful Gardener in Santa Fe

Sam Hitt's home in Santa Fe
America is full of "Master Gardeners" (a clever term that was purloined by the Extension Service for their trained volunteers--most of whom have a good mastery of basic gardening. But then there are people like Sam Hitt--who have truly mastered a wide range of garden styles and whose gardens are truly cutting edge. Here you can catch a glimpse of the front of Sam's amazing garden in front of his home in Santa Fe--a city in the midst of a severe drought where water rates are just about the highest in the country.

A closer look...
You can see the tubes where Sam has even had to use drip for his xeric plants!



Mammillaria geminispina along pathway
Not everything at Sam's is hardy: here you can see a truly breathtaking specimen of a Mammillaria, which I neglected to get a proper name for: this resides in the greenhouse for the winter!
 
Penstemon ambiguus
I envied his husky clump of Phlox penstemon (Penstemon ambiguus) which I find less than permanent in my garden. This is native around Santa Fe and is obviously at home here...



Veggies!
Sam is technically retired, but I am quite sure that his garden is a full time job: he sells greens and specializes in unusual edibles. His "farm" part of the garden is scattered among the xeric gardens--making for a great deal of interest and contrast as you walk around: this is a lollapalooza of a garden!


Sam pointing out some treasures
Here Sam is pointing out some xeric treasure to us in one of the many rock gardens...


One of Pete Hitt's stone troughs
Sam's son, Peter Hitt, creates spectacular troughs out of solid stone by cutting them himself. Here is a small example planted to Hens and Chicks.

TMore views of the xeric rock gardens
Troughs are often integrated into the garden, as it is above...


More veggie gardens
There was scarcely a weed anywhere (I picked one or two to show my helpfulness) and everything was neat as a pin...


Brand new garden area 
Sam had just cleared and prepared a large new area for veggies this last year since my last visit: it is truly pristine...that's a new greenhouse too!


The xeric rock gardens
Another view of a xeric rock garden: he had many penstemons and buckwheats I'd not seen before, and all manner of native steppe gems that are very challenging in my home garden. This would be  garden to see in April and May!


Cut flowers and greens
More veggies interspersed with some daylilies and other ornamentals: Sam lives in the middle of gorgeous, hilly, pinon juniper country--Santa Fe rocks!

Xeric rock gardens from another angle
Yet another view of the xeric rock gardens..

Parsley, sage, rosemary and thyme (sort of)
More veggies...

Leaf veggies protected from critters
Sam has a devil of a time with quail and thrashers--two very destructive birds: he has great stories about these and his garden....He's had to go to great strengths to protect certain veggie beds.


More goodies
We are living in a moment when sophisticated greens are very popular: Sam has done much of the R. and D. for these in Santa Fe: I ask him if he minds that other growers copy him. He tells me he is thrilled! This is one generous dude...


Queen Anne's Lace (wild carrots) are havens for beneficial insects (and great cut flowers)
He has one wicked little secret: he has found a huge market for self sown carrots: when these "Queen Anne's Lace" bloom, they are avidly sought after as cut flowers...he would grow them any way because they are living magnets for beneficial insects.


I love the way Sam intermixes ornamentals and food plants throughout this garden: it's so real!



Vibrant coors on hens and chicks
The hens and chicks kept wonderful color in his special greenhouse (usually this time of year they bleach out): he has an outstanding assortment.


Closeup
Don't ask me their names please: they were choice, just leave it at that!



Christmas trees of yore (including two magnificent Serbian spruce)
He and his family have had living Christmas trees for years: these are all former Christmas trees forming a bit of a forest. I was thrilled to see the two large specimens of Serbian Spruce (Picea omorica). Sam has these on drip--but even so I was amazed they grew so well in what is (after all) northerly Chihuahuan desert/steppe...

Compost teamaker
He had many depressing stories to tell about the many regulations that are making small operations like his harder and harder to operate. Even the compost tea has to have special containers and "federal oversite"!



Admiring Pseudolithos in full bloom
Here Sam is showing off a very challenging, tiny succulent from South Africa (Pseudolithos) with tiny mahogany red flowers. That's Maia Sampson Michael, who hosted us this past weekend: she and I have known each other since first grade!
Tender succulent container
Masterful gardeners grow all manner of plants, like these tender succulents!


Rock collection (for future container gardens...)

Sam and his son Pete do quite a business in container plants: here are lots of varied rocks and bones for future container gardens, I reckon!



Rock Spiraea  from the Grand Canyon
 
Sam collected seed of Petrophytum caespitosum (rock spiraea) near the Grand Canyon--which is growing in one of his wonderful walls just as it would in nature (he just scattered seed here)


Agave parryi
This is the only one of many agaves Sam grew that survived a viciously cold winter: he has propagated from this for years--I suspect we should publicize this super hardy clone of Agave parryi. Methinks this could bloom next year....

Leaf Amaranth: surprise success story
Sam was delighted to discover that there was a large market for leafy Amaranth--which can be used in salads as well as a summer potherb. He expects his competition to catch on to this quickly--I wish our local groceries would too!

Closeup of Amaranth



I just love these colors and textures!
One last glimpse of these fresh veggies: what a wonderful combination! Delicious greens and rare succulents and native plants, all grown to perfection!


Berlandiera growing wild
And wouldn't you know, here and there around his property there were massive clumps of Chocolate flower growing wild: I found these accidental wildlings as appealing as his wealth of "deliberate" plants--he's attempted to keep his fields wild as possible--and they are full of treasures like this. The chocolate smell, by the way, was quite overwhelming the morning we were there--what a wonderful fragrance to remind me of a great Gardener....and did I mention that Sam is well known in Santa Fe politics for his bold environmental stands and clear articulation of common sense? He's one of my heros--and I shall have to return to his garden in high spring (on a slightly overcast day) to do it more justice. As it is, Jan Fahs managed to get lots of great pictures anyway, despite the hot sun and advanced season...

The Andes: the last great hold out for Colorado horticulture!

Bolax glebaria in an old book print

A photograph taken in 1885 on the expedition of the H.M.S. Challenger on the Falkland Islands (or Malvinas--as your political persuasion my fall!)...a century and a half later, this Bolax glebaria has grown for decades in Colorado gardens, but precious else from the Andes or South America...why is this the case? Twenty years ago I was preparing for my first trip to South Africa--a place where equally few plants had proven hardy--but I had a hunch. Well, we have a hunch that South America may likewise prove to be a wonderful source of garden plants!


Alstroemeria umbellata
 This incredible cushion Alstroemeria is growing for Jane McGary in Oregon--and yet as you can see from the background, it is an alpine from Valle Nevado not far above Santiago at the latitude of Denver (albeit alpine!)--why do we not have this in our gardens? When I photographed this a decade ago I fantasized about the wealth of incredibly beautiful plants we would one day have here: and yet of the nearly 300 collections Nicola Ripley and I made back then, not one persists.


Calceolaria lanceolata
 Although I did grow this Calceolaria just as well--maybe better--for many years, where it formed two foot mats for me in Denver. But we eventually neglected to take cuttings or save seed and it was lost. I took this picture on screes above Laguna del Maule, where I walked for acres through wall to wall Viola cotyledon--in every vivid color and almost the size of pansies, plants forming mounds a foot or more across. I stroll through that meadow again and again in my mind...the violets were interspersed with Oxalis adenophylla, which thrives for us. What's up?


Montiopsis (Calandrinia) sericea
 I believe I photographed this at Lagunillas--another astonishingly beautiful alpine site in the Andes, chockablock full of treasures. I managed to get some seed, and Laporte Alpines grew it for years (see below)...


Montiopsis sericea (with Oxalis squamata in the background)
The Montiopsis proved not hard to grow--only trouble was no one bought it, and Kirk and Karen (those amazingly talented but sometimes misguided souls) dropped it. As they did the Andean Oxalis squamata which you can glimpse behind (because they were afraid it might become a weed I recall: weeds like that I can USE!)

I end on a positive note...
Sisyrinchium arenarium
 
Karen took cuttings of this a few years ago, and has produced numerous husky plants which are now prospering in many local gardens: so not everything is doom and gloom.
 
 
On July 27, two of the leading authorities on South American alpines and steppe plants are giving a dynamite seminar at the lofty and cool (and beautiful) Castle at Cherokee Ranch, one of Colorado's most beautiful venues. There are short tours of the castle, and some hikes in the amazing country nearby with panoramic views of Denver below and the stark spine of the Continental Divide: the two Marcelas who are presenting are filled with Latin fire: I believe this will be a historic occasion which will usher in a wonderful new world of hardy plants for our gardens.
 
My colleagues Dan Johnson and Mike Kintgen have taken several trips to research South American plants, and we have tested many that are in commerce--some day I predict our gardens will be full of gorgeous Phaiophleps, Rhodophiala and Azorella...not to mention mouth watering Alstroemeria and Calandrinia galore. The scenery and biodiversity of the Southern Andes is mind boggling--do join us at Cherokee Ranch next week...
 
Or if you are in the Steamboat area on July 20, the Marcelas will be speaking at the Trillium House at Yampa River Botanic Park at 3.30PM.
 
They are also presenting at the Gardens at Spring Creek in Fort Collins on July 25. You must make a reservation for that one too, however.
 
 
I was thrilled hearing the two of them speak Tuesday evening here at Denver Botanic Gardens: their depth of knowledge and passion for their work (and the delightful delivery) was over the top. Don't miss them!

Fatidicism....


I suspect I made up that word: I am not overly fatidic. but I copied below the fateful number that I just saw when I checked my blog:

America's great unknown alpines part one...Collomia!

Collomia debilis
To paraphrase Geoffrey Charlesworth, it's more important to have taken pictures than to merely have grown a plant. I have grown my share of collomias--a wonderful small genus in the Phlox family restricted to Western America (and just maybe South America too)...the one above originating in Idaho. It came to me as Collomia debilis ssp. trifidus--although Botanists have been busy lumping the subspecies into the generic species lately....I believe I grew this from seed sent to me by Betty Lowry: we're talking several decades ago! I'm glad I got the picture then--I kept it a year or two and it melted away...


Collomia larsenii
I have never grown the even more congested form of this wonderful plant from alpine heights on the Pacific coast--but these two shots should convince you that this is one of America's great alpines, with wonderful variation in color...


Collomia larsenii
All forms of this Collomia seem to grow on steep screes: "soboliferous" is the term used by botanists to characterize these plants. I have noticed that sobiliferous alpines are densely glandular and often intensely aromatic--often plants in different plant families can smell the same and have the same sticky hairs! And the seed seems to germinate sporadically in scree plants--who knows why?


Collomia ipomoea
This is the form predominating in Wyoming and Utah--a wonderful pink with longer trumpets. I have had the most success with this--perhaps because of its lower latitude and altitude...
 
Collomia ipomoea
These are all images scanned by Ann Frazier, a volunteer at Denver Botanic Gardens: I have not encountered this plant in either the wild nor in gardens since I switched to digital. I intend to be passing through its range in the next few weeks--and hope I can bring back a bounty of seed so I can see once again if these can be tamed a bit more permanently...
 
 There are other collomias--many of them annuals--well worth growing as well, but these three variations on the theme of debilis are the queens of the genus--and possibly three of the most promising wild flowers that still elude our gardens!

The mountains rock (quite literally)...

Black boulders from China
There are clever people who live at over 8000' a short drive from Denver so that when we are parboiling on summer afternoons, they're basking in cooler clime. We are fortunate to know a remarkable couple who live near Conifer and  who have created an extravaganza of a home and garden we have enjoyed over the years: here you can see some of the many enormous rocks that Robert has had shipped from China that he has highlighted in his amazing Oriental garden...

Robert and with a glimpse of Tai Hu rock to the left...
 There are galleries here and there in the Ponderosa woodland featuring these monumental rocks...

His latest acquisition from China
 He enjoys watching my jaw drop each year when he reveals yet another magnificent rock: this Tai Hu gem was just installed. If you are not aware, Lake T'ai (太湖 (Tai Hu) in Chinese) is the source for these Henry Moore megaliths that are featured in many of the greatest Chinese gardens, like the garden of the Nets and Humble Administrator's garden in Suzhou. I suspect you would have to go thousand miles or more to encounter another such rock in America...


More Tai Hu monoliths and flowers
 Except of course from those Robert obtained in earlier years. Early July is a slow time in Denver gardens, but the height of late spring-early summer bloom in Conifer!


Geranium sanguineum dwarf form
 The geraniums are mostly past peak in Denver, but still blazing in the Montane.

ANOTHER cluster of classic stones...
This cluster of monoliths is set off with a lovely meadow geranium's blue color...

Robert leading us along the way


A newly acquired antique sculpture


This sculpture has been in place for as long as I recall, however..


Some other guests in one of the flower gardens


Art in the garden
 In addition to being garden connoisseurs, Robert and Lisa are lovers of art--both in their house and in the garden. I always do a double take seeing a bookshelf in the garden...


A number of their sculptures are quite funny...


Artemisia ludoviciana
 I was especially taken with this nice bank of Louisiana sage...


Flags connote the recent National holiday outside a guest cottage


The many elaborate containers are largely due to their having a large greenhouse on site.


Bocce  ball, anyone?


Sculpture of all kinds...

I always chuckle when I walk by this one...


Not everyone can have a 9 hole golf course on their property!

The engine on the functioning Model T fascinates us...


A last glimpse of the newly installed scholars on the lawn...


Suseki
I know many locals are beginning to collect viewing stones--but this must be the largest and most dazzling in the state!

Thank you, Robert and Lisa, for yet another enchanting Sunday in Coolorado!
