Aloe vera, also known as the medicinal aloe, is a species of succulent plant that probably originated in Northern Africa, the Canary islands and Cape Verde. Aloe vera grows in arid climates and is widely distributed in Africa and other arid areas. The species is frequently cited as being used in herbal medicine.
Aloe vera is a stemless or very short-stemmed succulent plant growing to 60–100 cm (24–39 in) tall, spreading by offsets. The leaves are thick and fleshy, green to grey-green, with some varieties showing white flecks on the upper and lower stem surfaces.[1] The margin of the leaf is serrated and has small white teeth. The flowers are produced in summer on a spike up to 90 cm in tall, each flower pendulous, with a yellow tubular corolla 2–3 cm (0.8–1.2 in) long.[1][2] Like other Aloe species, Aloe vera forms arbuscular mycorrhiza, a symbiosis that allows the plant better access to mineral nutrients in soil.[3]

Cultivation
Aloe vera has been widely grown as an ornamental plant. The species is popular with modern gardeners as a putatively medicinal plant and due to its interesting flowers, form and succulence. This succulence enables the species to survive in areas of low natural rainfall, making it ideal for rockeries and other low-water use gardens.[1] The species is hardy in zones 8–11, although it is intolerant of very heavy frost or snow.[2][4]
In pots, the species requires well-drained sandy potting soil and bright sunny conditions. The use of a good quality commercial propagation mix or pre-packaged "cacti and succulent mix" is recommended as they allow good drainage.[5] Terracotta pots are preferable as they are porous.[5] Potted plants should be allowed to completely dry prior to re-watering. During winter, A. vera may become dormant, during which little moisture is required. In areas that receive frost or snow the species is best kept indoors or in heated glasshouses.[2]
