Aloes

Aloes are a genus of succulent flowering plants in the family Asphodelaceae. The genus comprises about 500 species, native mainly to Africa, with some occurring in the Arabian Peninsula and on islands in the Indian Ocean.

They form rosettes of thick, fleshy leaves with sharp teeth along the margins; leaf color ranges from gray-green to bright green and may be mottled or variegated in some species. Flower stalks bear tubular flowers in shades of yellow, orange, or red and can attract pollinators such as birds and insects.

Adapted to arid and semi-arid environments, many species prefer well-drained soils; they are drought-tolerant and some tolerate light frost.

Aloe vera is the best-known species; its gel is used in cosmetics and skin-care products; the yellow sap (latex) contains aloin and has historically been used as a laxative, though its internal use is restricted due to safety concerns.

Other species are used in traditional medicine in Africa; aloes are widely cultivated as ornamentals in gardens and containers, valued for their architectural form and drought tolerance.

In cultivation, provide full sun and sparse watering; use well-drained, sandy or gritty soil; protect from freezing temperatures in colder regions. Propagation is usually by offsetting pups or, less commonly, by leaf cuttings, in warm conditions.

Taxonomically, Aloe is placed in the family Asphodelaceae, with numerous species and many cultivars and hybrids.
