I have several Lewisia planted in my garden, they are all in the same general area at the top of a planter wall, they are beautiful. I can't tell if they will all come back this year. It seems I may have lost 1 or 2 over a period of 5 years so I consider them well worth it. I am located in Los Gatos, on the South side of San Jose, CA. Think of this as zone 9, maybe the chillier side of zone 9 Carolyn
