surpise lilies from trade
I have a question. I am in zone 5 and I traded for some surpise lilies from someone in a warmer zone. The stems have now turned yellow and it looks like they are dying. By the way, I planted them in pots in the house for now. Is it alright to plant them outside now, even though it may frost yet? I have never had these but they are beautiful. Also, I think I read somewhere that these are hardy in my zone 5. Is that correct? Thank you in advance for you help.
