The plant carries up to 12 branches with bulbs that vary in color from green-yellow, orange, or dull red.[Hans Dieter Neuwinger African Ethnobotany: Poisons and Drugs: Chemistry, Pharmacology, Toxicology (Chapman & Hall 1996) pg 7]
Genetics and breeding
The chromosome number of Aloe buettneri is 2n=14. Except for Aloe vera, all Aloe species, including Aloe buettneri, are listed by CITES, and trade in plants and plant parts is restricted.
