Crassula justus

Crassula × justus is a garden hybrid published by Corderoy in 1904, not a wild species, so there is no native habitat to copy. GBIF holds no wild records for it; grow it like the small rosette-forming Cape crassulas it was bred from, in bright light with cool nights and careful watering.
