I love aeoniums and would love to create a display similar to this (from Sarah Price's show garden at last year's Chelsea). Obviously they're not hardy so you'd have to bring a big pot in for the winter (or into a greenhouse, which I don't have), or maybe protected outdoors with fleece/straw/hessian (?). And the ones in the ground would have to be dug up (?).
Anyway, I did try recreating the pot using a large galvanised container, and it looked amazing, but alas the tallest aeonium snapped. How the jeff do people grow tall aeoniums (like the one on the left in the ground) without them snapping? Surely it must be possible as the tree aeoniums must get huge in the wild? Any tips from aeonium lovers would be gratefully received
