The smaller form occurs in the Eastern Cape from Somerset East to Port Elizabeth, the robust form grows in the southwestern districts near Oudtshoorn. It is a very distinctive small aloe with greyish-green leaves which are tuberculate and have soft prickles on both surfaces, the margins having soft white teeth. It forms dense low clumps with scarlet flowers; the open flowers are pendulous, with conspicuous large bracts. Less common is the orange-flowered form from Hankey in the Eastern Cape. Flowering from August to September.

South Africa Cape of Good Hope, without precise locality. Iconotype: C. Commelijn, Hort. Med. Amst. Plant. Rar.: tab. 46 (1706).
A. humilis had a wide distribution in the south-eastern districts of the Western Cape and in the western half of Eastern Cape province, in karoid bush and similar semi-arid biomes. It is quite variable and at least five of its more distintive forms have, at various times, been assigned varietal rank, based principally on size. A. humilis is known extensively in cultivation as an attractive and easily grown dwarf plant. In the wild, some of its many forms tend to produce very large clusters of closely set rosettes. When in flower, these groups are most attractive.
