Aloe falcata is closely related to Aloe claviflora. Aloe falcata has similar asymmetrical rosettes but the inflorescenses are branched and erect however and the growth habit differs in that the older plants do not die off in the middle of the clusters.
Aloe falcata grows in the sandy desert plains of the western parts of the Northern Cape extending southwards into the Western Cape up to Klawer.
The plants do not adapt well outside their natural habitat.
The flowers of Aloe falcata are usually red in colour but sometimes yellow.
