My rain lily grew a new stalk
I had only 2 rain lilies last year, and kept them in some very small pot with regular dirt (not even potting soil). I did this since I didn't know much about them yet and it was more like growing to see if I'd like it or not.
Turns out that I do like them, and they actually overwintered in the garage without losing any leaves, so there didn't seem to be a particular dormant period where I might repot or replant them.
However, this year, I see the beginnings of another stalk coming out near the parent. Not sure if that would be another bulb or stalk from same bulb, but it's good that now there will be at least 3 flowering stalks.
Pretty happy about that, as well as knowing that they might naturalize well if planted out in the yard somewhere.
