I've got lots of these, grown from seed this winter... any opinions on whether they really are Androsace spinulifera?
I recall from this post that Androsace spinulifera takes on its spiny appearance with the winter resting buds:
The leaves on my plants are slightly toothed and Doreen's were not.
However, I note that these seedlings do look quite similar to the product of the Androsace fedtschenkoi seed that I bought from the same vendor:
I'd say no -- I have pictures of Androsace spinulifera in the wild in China and your seedling's leaves don't match at all.
Rats! Between the A. fedtschenkoi and whatever this is, if not more of the same, I've got about two dozen not-quite-what-I-had-in-mind Androsace seedlings.... yikes. ;-)
