Hi folks, I don't usually grow succulents, but I just couldn't pass this one up when I saw it at Home Depot. It's named Echeveria 'Surf' and when I bought it this past winter, it was a rosette of purple leaves, I mean purple like grape kool-aid or a classic bearded iris or purple lavender. Gradually the leaves faded though. It is now outside for the summer, on an east-facing porch, and the new leaves coming in are a pale purplish gray. Very nice, but I am wondering - how on earth did the grower get it to be that purple?
