I've looked through my seed-starting lists from the last 3 years a couple of times, but can't make the link to this plant shown below - obviously a Caryophyllaceae, I'd guess Gypsophila or maybe Cerastium? Anyone recognize it?
Those are not the greatest photos for IDs... I'll get some better ones. Thanks in advance.
Indeed, very close! It turns
Indeed, very close! It turns out that it ought to be Cerastium latifolium, started in 2010 - I didn't go back far enough in my seed-starting notes. Funny that it took that long to bloom! Thank you very much for the great clue.
My guess is a Cerastium alpinum or a close relative of that.
