Greg, Jo Ann's semp is not S. 'Keston'. If that is where you got yours it is not correct.
S. 'Keston' is not in our database. I don't know if it is even in the U.S. at this time.
This is what it should look like:
http://sempervivum-liste.de/Se...
And this is all that is know about it.
Breeder unknown / named by Alan C. Smith / GB / parent. grandiflorum / syn. 'Leave's Gree'
Nothing about the circumstances of where he found it or anything. Could even be one of the already identified S. grandiflorum.
