Adenium swazicun

This is supposed to be the hardiest Adenium. It is also a very free blooming species with intense pink flowers borne in masses that tends to have a longer flowering season than most of the Adeniums.
Description: It is a dwarf shrub, up to 30 cm high, with an enlarged succulent stem with few branches, sometimes partly below ground that tend to droop or spread, especially in plants that are too shaded; mature plants have massive roots and thick stems, but a caudex is evident only in young ones.
Flower: Uniformly colored pink to deep reddish purple, blooming over a long season normally in late summer and autumn.
