Many thanks to each of you for the advice. I put them close together and put mulch around the outside of the group. I didn't know about the water. I think I'm in zone 8, but we do get some low temps and the last couple of years snow. Last week, temperatures were in the high 20's, low 30's; dog's water froze a thin sheet of ice, but today, it was windy but warm with a forecast for the low 80's tomorrow. Again, thanks. I'm trying to save some plants and have limited knowledge, so all advice is welcomed.
