Agave americana, the Century Plant, is a large, dramatic succulent forming a bold rosette of thick, sword-shaped blue-grey leaves edged with sharp spines and tipped with a stiff terminal spike. Native to Mexico and now widely naturalised in India, it is exceptionally drought- and heat-tolerant, thriving in poor soils and full sun. After many years a mature plant sends up a towering flower stalk, then dies, leaving behind numerous offsets. Its architectural form suits xeriscapes, large pots, slopes and dry borders. Striking and nearly indestructible, it is ideal for low-water Indian landscapes, though its spines need careful siting.

Growing tips
In India plant it in full sun in well-drained or sandy soil; it needs almost no care once established, but site it away from paths because of its sharp spines.
