Of all the succulents I have collected, aeoniums have been the most up and down. Their peak was in 2009, at which time I owned 10 - 15 different varieties. Sadly loses over winter showed how difficult they were to keep in the UK, needing above -3 to survive. So I have not been replacing them and anyone who shows interests in one of my plants often leaves with it. Going into last winter I had 4 left, two of which have since been given away, leaving me with my cristate a.suburst (which I posted about here) and a. nobile.
Personally I think they are one if not the best aeonium, well worth the pampering you have to give them over winter. This is one aeonium that is going to start in my collection, so hands off.
