Clanwilliam aloe is a tree-like succulent from the Western Cape of South Africa, growing as a single unbranched stem topped with a rosette of thick, spiny-edged leaves. It needs bright light, very sharp drainage and minimal water, and is best kept as a bright houseplant or collector's plant.

About
Aloe comosa is a species of flowering plant in the Asphodelaceae family. It is commonly called Clanwilliam aloe and is endemic to South Africa.
Where it grows
Aloe comosa inhabits a very small region within the Western Cape province of South Africa. It was discovered in the Olifants River Valley in 1905, north of the town Clanwilliam (hence its common name).
Uses
The genus Aloe currently consists of over 650 species. A few species of aloe are used to treat minor thermal burns, itching, and sunburn by applying the thick, mucilaginous gel to the skin, but Aloe comosa is not one of those species. Its only apparent uses are a decorative house plant and collector's item. Even though Aloe comosa is indigenous to the Western Cape of South Africa, it is possible for experienced collectors and horticulturalists to maintain their plants outdoors, in Arizona and California for instance, or in a desert climate greenhouse.
