A good tough drought tolerant plant for a dry garden or seaside garden and as with other Rockroses, it is resistant to deer predation, tolerates heat, poor soil and its flowers are attractive to butterflies.
Cistus ladanifer var. petiolatus is the botanical name under which 'Bennett's White' is usually marketed as a cultivar of but current treatment considers this species to be a synonym of Cistus ladanifer subspecies mauritianus, which grows naturally from Spain on the European continent south into Algeria and Morocco in North Africa. The name Cistus is from the Greek word 'kistos' which was the name originally used to describe the plant in ancient Greece. The specific epithet 'ladanifer' given to this plant by Linnaeus literally means "bearing of ladanum" - for more information about the reason for this name see our listing of Cistus ladanifer. We also grow the similar but taller and more open Cistus ladanifer 'Blanche'.
