Family: Desert Rose, Desert Azalea, Impala Lily, Sabie Star, APOCYNACEAE
Named for the former British colony of Aden, part of its natural territory, the gorgeously flowering Desert Rose (Adenium obesum) resembles and is closely related to the Frangipani. A 2m/6ft tall, sparsely branched shrub in nature, with a swollen trunk base, it is more often seen in cultivation as a rather dwarfed pot plant.
More drought resistant than Frangipani, it is propagated from dried-off branches struck in damp sand. Adeniums are evergreen in a warm climate, but it is useless to try them where there is frost. The leaves are glossy; oval but widest at the tips.
Flowers in winter-spring are a brilliant scarlet-pink, centred with white and yellow, and borne in terminal clusters. They like a dry winter, good drainage.
