David, I think I may have just killed my Lewisia
Do not know if I want to try them again..they really were beautiful, though I am still hoping it is just being rather late in coming back from its summer slumber. I have not yet tossed them out, will wait till January if it will revive. Just when I thought I finally understood what it needs..but not losing hope yet..
I had two other plants Radermachera sinica and my milkweed, Asclepias currasavica-badly attacked by aphids this summer, seemed to be on the brink of annihilation, but surprisingly is growing well again now. A wait and see game!
