Sabine, look at the different places to go next to the blue house icon at top of your home page.
1) Click on the arrow next to Plants Database
2) On the right, click on the database "Sempervivum" (given as 1 of top-most search)
3) Then click on Serach by Characteristics (ht, bloom, etc)
4) Fill in the boxes for Hybrid, check yes and for Hybridizer, enter name and press Search box.
for example, check the Hybrid yes box and enter "Kevin Vaughn" and you will get a list of his hybrids, "Black Lotus', 'Blue Whale', etc
The lists may not be complete as there's always a hybrid in process of being introduced or loaded into a database.
