Both subspecies of this plant have been introduced to Australia where "A. g. micrantha" is on the National Environmental Alert List and must be reported when found. The original range of the subspecies is unclear, but it is likely that "A. g. gangetica" was limited to Asia, and "A. g. micrantha" was limited to Africa.

Flower production can begin as early as 40 days after germination, with seed development beginning
