Wenatchee Mountains

[Spiegel]

I think some of the plants that grow so well with tufa may simply like the better supply of moisture and can be tolerant of lime.  It's amazing the wide range of plants that seem to grow well near or in tufa.

Wonderful topic; I've wanted to respond but have been way too busy. David, wonderful photos of great plants!

When I lived in the Seattle Washington area from 1982-86, my favorite botanizing haunts included the Wenatchee Mts... the memory stream back when I see these images in this thread.  I have often wondered why only the typical apricot-pinkish form of Lewisia tweedyi was in cultivation, when there are some incredible yellow forms and yellow-strongly-tinged-red forms.  For some reason two plants always come to mind when I think of the Wenatchees; Penstemon gairdneri, like small bonsai shrubs in two color forms; an intense purplish form, but it was the clear deep blues that I liked best, and Eriogonum douglasii (in a narrow rolled-leaf form that corresponds to the entity "var. tenue") that came in every color from cream to incredible candy pinks to raspberry reds among dwarf mats of ash-silver foliage.

Wonderful pictures again! I particularly liked the Lomatium!!

David, I loved your report and photos from the Wenatchee Mountains - have tried to grow Douglasias and Claytonias here without luck (if you can't grow them out there near their native habitat, I probably don't have a hope of success out here with them).  I did have some success with a Calochortus bulb one time - planted it VERY deep on a south facing slope and it did well for a couple of years and then just disppeared.  Would very much like to have more of them but have steered clear of ordering seeds from the Seedex as they take such a long time to reach flowering stage (as do all lilies in my experience) and, at my age, there just isn't enough time for the 'slow pokes'.  Fran

Following this with great interest. Would I be wasting my time trying some Douglasia and Claytonia outside here in my wet(very) Zone 9b and would they take to pot cultivation under glass?

David/Fran:

I have had Douglasia laevigata growing outside for about 8 years.  The flowering is not spectacular though - nothing like in the wild. I tried Claytonia megarhiza outside and Douglasia nivalis but they soon packed it in.  I am now trying Douglasia nivalis in a sunnier spot in the garden among bits of tufa.  So far it looks good but they have to survive a wet winter yet.

Pot cultivation under glass is definitely easier. I have had Claytonia megarhiza v nivalis  for several years in the plunge bed in my Alpine Shed and have had good flowers.  Douglasia nivalis is also quite easy in a pot.  This one was from seed from Chumstick Mountain a couple of years ago and it flowered beautifully last Spring.

Thanks David, i'll be looking out for both.

Just managed to get hold of a small plant of Claytonia megarhiza v. nivalis so David, if you're reading this any tips on compost, method etc. for growing under glass would be much appreciated. Managed to get hold of a small plant of Douglasia montana too

Hi David,
Claytonia megarhiza v. nivalis grows and flowers well in a medium sized pot here in Lancashire.  It stays outside (i.e. no cover whatsoever) from the end of April until October and then in an open-sided frame throughout the winter.  It is in a very gritty compost with pebbles incorporated into the mix. It has self-seeded into adjoining pots, but these seedlings don't transplant very easily.  I might be tempted to sow some of your seed onto a large pot capable of supporting these deep rooted plants for their lifetime.

Hi Cliff,

Many thanks for that. Does it mind lime please?

[David Sellars]

David:
My potting mix for pots in the Alpine Shed is mostly coarse sand with about 15 -25% crusher fines and a little bit of pH corrected peat. We can't get John Innes composts here so we have to make it up as we go along. The crusher fines have lots of mineral nutrients which I think is a real bonus. Because I have no soil at all in the mix I occasionally add a bit of fertilizer.
 
My experiment with a sunny sand bed with lumps of tufa and sub-irrigation is working well.  The Douglasia nivalis survived the soggy, wet winter and produced quite a few flowers (see below). I planted Claytonia megarhiza v nivalis last spring in a similar location and it is doing fine but has not yet been though a winter. Both plants grow in serpentine areas in the Wenatchee Mountains so are pretty tough. There is no limestone anywhere near where they grow but they don't seem to mind growing among lumps of tufa. There may not be much or any lime released by the tufa though.

[Booker]

That is a very interesting growing regime David and it appears to be working well.  I suspect that the Claytonia will tolerate (but certainly not require) a modicum of lime.  I don't purposely introduce lime, but there may be a little released by the mixed pebbles that I include. Be wary of pampering them too much Mr. N. ... like a great many alpines they repay neglect and disdain, well they do in my garden anyway!

Great info, David.  Is Douglasia nivalis more difficult to grow than D. montana?

[David Sellars]

Lori:

I have certainly found Douglasia nivalis easier to grow than Douglasia montana. Mind you the Douglasia montana I have had were purchased plants and it may do better from a seed grown plant (or at least you have more plants so you can accept a few losses   )  Most Androsaces seem to come easily from seed and Douglasia nivalis is no exception.  I have attempted to grow Douglasia montana with seed from the Androsace Group of the AGS. They grew very well but turned out to be a hybrid of Androsace carnea  .

Wild seed of Douglasia nivalis is currently available through the Alpine Garden Club of British Columbia Seed Exchange.

Douglasia montana seems to grow pretty easily here (not to claim I grow it particularly well however)... it does seem to bode well for growing D. nivalis, though.  I will look out for it.
