Disphyma crassifolium (Purple Dewplant)
This procumbent, succulent, semi-woody perennial is often grown in gardens in mild, coastal areas and has become well naturalised on walls, cliffs and sandy places near the sea. In Jersey, it also grows under conifers and in a salt marsh. Elsewhere, it occurs as a wool shoddy casual. Although viable seed is produced, reproduction in Britain is from the rooting of detached stem fragments. Lowland.
This species, known to be in cultivation in Britain by 1727, was first recorded as naturalised in 1936 on Tresco, Isles of Scilly.
Native of Cape Province, S. Africa; similar (possibly conspecific) taxa occur in Australasia.
Supralittoral rock (does not include maritime grassland)
Supralittoral sediment (strandlines, shingle, coastal dunes)
