Agave Americana, sentry plant, century plant or American aloe, is a species of flowering plant native to Mexico, and the United States in New Mexico, Arizona and Texas.
It typically lives only 10 to 30 years. It has a spread around 6–10 ft (1.8–3.0 m) with gray-green leaves of 3–5 ft (0.9–1.5 m) long, each with a prickly margin and a heavy spike at the tip that can pierce deeply. Near the end of its life, the plant sends up a tall, branched stalk, laden with yellow blossoms that may reach a total height up to 25–30 ft (8–9 m) tall.
Agave Americana is cultivated as an ornamental plant for the large dramatic form of mature plants—for modernist, drought tolerant, and desert-style cactus gardens—among many planted settings. It is often used in hot climates and where drought conditions occur.
Agave Americana is beautiful focus plants for any succulent garden.
