Here is another awesome series of sempervivum, by an American hybridizer and owner of SMG Succulents.
Gingerbread Boy
Jeepers Creepers (not yet released)
Lush Life (not yet released)
Midnight Sun
New Rhumba
Nightcrawler (not yet released)
Round Midnight
Salt Peanuts
Sophisticated Lady (not yet released)
I have two of this series so far, and can't wait to collect the rest of them.
Both Gingerbread Boy and New Rhumba are outstanding semps.
Newly acquired S. 'Gingerbread Boy', as a young plant. Can't wait to see this one mature and go through all the seasons.
