Aloe

Aloe, genus of succulent plants with more than 150 species, most native to southern Africa. They usually have short stems, fleshy, tapering leaves crowded in rosettes at the end of the stem, and red or yellow tubular flowers in dense clusters. Species vary in height from several centimetres to more than 9 m (30 ft); they are widely cultivated as garden and tub plants in warmer regions. Several species are commercially important as the source of the bitter-tasting aloes used in medicine.
