Looks like there are 2 threads going for this plant ID:
The thread "NOID from a mix?" in
Wildflowers forum
From the other thread:
Caroline: "I am bumping this thread up as I don't want the wrong ID to go in database.
I think that it is Mountain Phlox Linanthus Grandiflora ???"
Me: "Looks like it. The name is now
Leptosiphon grandiflorus. So did it winter over for you? If it did, it would suggest it's a different species, as
Leptosiphon grandiflorus is an annual. I'm growing a couple of
Leptosiphon species, so if it is a perennial species, it might be hardy - who knows?"
