Argyroderma delaetii

Argyrodermas belong to the Ice Plant Family (Aizoaceae), and like most members of the family they are native to southern Africa. In particular, they favor quartz-fields in a dry area known as the Knersvlakte in western South Africa. Argyroderma delaetii is variable in flower color, but our pair pictured here have white flowers.
