Cok & Ine Grootscholten - Succulenta

http://www.succulenta-kwekerij.nl/

I visited this well known nursery last weekend. They specialize in succulents from warmer climates, but also offer houseleeks for sale. Part of their plants are lost-label, but they also have named cultivars (including at least one they named) and some wild houseleeks.

They have an online photoalbum here:
