Should be watered once every 1 to 2 weeks during the summer, keep dry in winter. The caudex can grow quite rapidly if over potted and kept in extremely well draining medium (mostly pumice), up to several inches a season.
A note on nomenclature:
Due to precedence, the accepted name for Adenium arabicum is Adenium obesum, however, this is the same name that was given to a genetically and visibly distinctive species originating from eastern Tanzania. This nomenclatural error (which is not resolved) has resulted in much confusion in the botanical community. Due to this, the majority of plants sold under these names are most likely hybrids between the two species.

This nomenclatural error (which is not resolved) has resulted in much confusion in the botanical community. Due to this, the majority of plants sold under these names are most likely hybrids between the two species.
