| I assume you mean Lewisia nevadensis? If so, I have grown them from seed a couple of times (including this spring). All Lewisia seed IME require cold stratification to germinate, so if you do get seed from your plant(s) you'll need to stratify the seed to germinate it. The question is, will you get seed? The plant flowered on your windowsill, did you have insects pollinate the flowers, or pollinate the flowers by hand? I don't know if Lewisia is wind pollinated, but I would guess they require bees, etc. to visit the flowers to get viable seed. Someone who grows alpines indoors should weigh in here to answer that question for you, I don't know. |
