This Orostachy I was told to keep it under cover for the winter, as it is very susceptible to water damage here in the PNW. I kept it on my covered deck for the winter and put it out in the raised beds this spring. It is doing well. All the others have been outdoors all winter in the raised beds. They really do shrink down to almost being invisible during the winter. My raised beds drain well even though we have months of nonstop rain and rarely any snow.
