Title: Parnassia foliosa var. foliosa ??
Post by: Jonny_SE on December 16, 2013, 12:51:13 PM

Anyone who can say anything about this one? Just got a few plants and my experience on this are to say at least extremely limited.
Not much to pick up on Google except moist welldrained. //Jonny

Perhaps we need some advice from Japanese members on this plant, Jonny.
I don't think I have even seen it.  :-\

Grass of Parnassus (Parnassia palustris) is of course a British native - see http://www.plant-identification.co.uk/skye/parnassiaceae/parnassia-palustris.htm (http://www.plant-identification.co.uk/skye/parnassiaceae/parnassia-palustris.htm)

There is a nice little article in one of the old AGS Bulletins (Vol. 33) by Richard Nutt on the British wintergreens. He mentions Clarence Elliott growing Pyrola rotundifolia in 18 inches of pure leafmould. Another grower grew P. uniflora in leafmould, pine needles and sand. Probably more of a problem is growing them successfully from seed so they can become available to gardeners; in earlier times they must have simply been lifted from the wild.

Why did I think of Pyrola? Must be because they are ecologically similar in my mind! Both fascinating plants that I have never really come across.

I don't know Parnassia foliosa var. foliosa but am very familiar with the European Grass of Parnassus which I have successfully transplanted into my mountain garden.
In the wild it grows both very wet but never in stagnant water, or rather dry but always in calcareous soil. It is often associated with plants like Saxifraga aizoides and Gentianella campestris, and also Dryas octopetala.
