Vegetative characteristics
Aloe haworthioides grows without a stem, is solitary or sprouting and then forming dense groups. Their roots are spindle-shaped. The approximately 30 narrow, lanceolate-deltoid leaves form dense rosettes . Your dark gray-green leaf blade is 3 to 4 inches long. The tip of the leaf is short and translucent. There are many white pustules on the leaf surface, each of which is occasionally tipped with a short white hair . The narrow deltoid, soft to firm, white teeth are 1 to 2 millimeters long and are crowded on the leaf margin.
Inflorescences and flowers
The simple inflorescence is 20 to 30 centimeters long. The rather dense, cylindrical and slightly tapering grapes are 4 to 6 inches long and 1.2 inches wide. They consist of 20 to 30 flowers . The almost circular, blunt bracts have a short pointed tip and are 5 millimeters long. Flower stalks are absent or negligibly short. The white to light pink, slightly bell-shaped flowers are 6 to 8 millimeters long. Your outer tepals are not fused together. The stamens and the stylus protrude 5 millimeters from the flower.

- Aloe haworthioides var. Haworthioides
