Pachyveria 'Blue Pearl' in bloom..

Your Blue Pearl is indeed different. I find succulents can be quite addictive & vary according to the cross breeding. I have Graptopetalum Ghost plant & Echevaria glauca. They all look quite similar.

Some of the Echevaria's are being sold now are getting very much different from wild species..big plants,don't like hot sun like many would think,and sort of look regal.
I bought a E. derigida, a little worn by customers at the nursery..but I thought "Better get it or it could be years before you see another".
You know how that goes.

I do indeed. Get it when you see it is a good policy.
