Aloe vera has been widely grown as an ornamental plant. The species is popular with modern gardeners as a putatively medicinal plant and for 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.[4] The species is hardy in zones 8–11, and is intolerant of heavy frost and snow.[5][28] The species is relatively resistant to most insect pests, though spider mites, mealy bugs, scale insects, and aphid species may cause a decline in plant health.[29][30] This plant has gained the Royal Horticultural Society’s Award of Garden Merit.[31]
In pots, the species requires well-drained, sandy potting soil and bright, sunny conditions. Aloe plants can burn under too much sun or shrivel when the pot does not drain water. The use of a good-quality commercial propagation mix or packaged “cacti and succulent mix” is recommended, as they allow good drainage.[32] Terra cotta pots are preferable as they are porous.[32] Potted plants should be allowed to completely dry before rewatering. When potted, aloes can become crowded with “pups” growing from the sides of the “mother plant”. Plants that have become crowded should be divided and repotted to allow room for further growth and help prevent pest infestations. During winter, Aloe 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.[5]
