Small green aloe with incurved leaves that have striking black spines along their margins and undersides. May be solitary or offsetting. From arid northwestern South Africa, a winter rainfall area. Red flowers opening to pale yellow appear on unbranched inflorescences in late fall/early winter. Leaves have a distinctly rough texture. Rosettes will close up on themselves and turn brown with drought stress.

Provide strong light and excellent drainage. Well suited to dry Mediterranean (winter rainfall) climates.

Aloe melanacantha can be distinguished from the closely related Aloe erinacea found to its north in Namibia based on bigger size, green color, and rough leaf texture. Aloe erinacea has formerly been treated as a variety of melanacantha.

Hybrids retain the rough leaf texture.
