Yes please do keep posted on here - I do like to hear what people are doing! If you are on FB there is a group called Planet Sempervivum and there is someone on there from Alberta CA I think, and he was wondering what people do in winter in those lower zones. I personally think these plants would do fine, especially in rockery, where it is more likely that water will drain away quickly - during the melts and refreezing periods, where the plant would be saturated for a time - this is hard on semps.
Also Nico please join us on the chat forum
