Coastal dunes or rocks.
This species has lost habitat to urban expansion on the Cape Flats and Cape Peninsula in the past. It continues to be threatened by coastal development on the Vredenburg Peninsula. Subpopulations around Mamre and Atlantis are also threatened by competition from alien invasive plants.

A very common species on dunes along the Cape West Coast. In spite of extensive habitat loss, a large number of recent records indicate that it still persists in at least 20 locations. Sporadic losses of individuals to development continues.
