Mystery silene

Submitted by Lori S. on Tue, 07/13/2010 - 20:41

I planted this as "Silene jenisseensis", but while this plant is supposed to form a hard dome, my did not and was stoloniferous to boot... I pulled it out this spring (and sprigs are still coming up here and there). It blooms in late summer here. Foliage got to about 4" tall, reddish on emergence in spring. Any idea what it actually is?

Edit:
Hmm, on second thought, maybe the other report ("hard dome") is wrong too? I'm confused!!
Here's the eFlora of China description - foliage on my plant seems not out of line:

And photos - the petal shape, flower size(?) and possibly the flower arrangement are not like mine, though:

Lori, your plant seems consistent with the Flora of China description, including the height (not sure about the "hard dome" description, was that a nurseryman or seed list description?).  The most compelling is the exserted trifid style, which can be clearly seen in your plant.  The Chinese photo is top down, so hard to gauge height.  The Flora of China also mentions that this is a "difficult group" involving several species, so maybe is rather variable.  I'd like to see a photo of the "slightly inflated" calyxes, the calyx characteristics so important in Silene and Saponaria for identification.

Lori, you really know how to do your homework and find links and photos!  Based on the second two links, I don't think this species is attractiveness enough to warrant risking a stoloniferous or otherwise spreading Silene in the garden; I would be tempted to toss it.
