Mark, I'm only guessing because I know Albuca shawii is from the Drakensburg, but I don't think it's likely to make it here as hardy. Cool greenhouse--yes. Covered frame--possible. But outside, I have my doubts. My albuca are grown indoors as pot plants, where they do fine and persist. Carlo Carlo A.
