WOW! That's a lot! I have many too, but wouldn't know their names and only two varieties. I'd be happy to share, but with 70 varieties you probably already have the ones I've got. LOL!

I've blogged them some from my rock garden here:

Here is a link that might be useful: my blog

I have about 40?? Only about half are named.

I am working on a better rock garden desing and then will probably get more.

Would love to trade.

Madtripper,

I would love to trade with you if you wish. Could you email me privately?

valleyrimgirl,

I live in NY state, zone 5b. I have a few sedums and Hens and Chicks (green and reddish), but have no larger sempervivums. Which larger ones survive reliably in my zone, and which nursery sells those in the US?
Thanks!
Bernd

Bernd,

I have not bought semps from any nursery in the US but Squaw Mountains in Oregon is one of the sites I have in my favorites as they have quite the selection of sempervivums. There is a picture of the semp as well as a description of the coloring and its size. Large semps they classify as getting to 2.5" in diameter or more.

Jack from Cavendish Perennials in Ontario would be also living in a zone 5ish just like you are. So, any semps he can grow you should be able to also. If you go to his web site...

in his catalogue you can get a description of the semp and its size also.

Then go to the Squaw Mountain site for pictures or to this Yahoo group site...

I have now purchased about 150 different kinds from Cavendish Perennials in the past years with another 50 varieties coming again this spring. All the semps I have gotten from Jack have been fully winterhardy here in my Canadian zone 2b yard.

Let us know which ones you choose and where you ordered them from.
