Agave atrovirens var. atrovirens

A large, robust agave species native to the high-altitude regions of central and southern Mexico. This agave is notable for its size, with broad, fleshy leaves that form a striking rosette. It produces a tall flowering stalk that can grow over 6 meters (20 feet) in height in the wild. The flowers are typically yellow-green and appear after several years of growth. The plant is monocarpic, meaning it flowers once and then dies, though it often produces offsets before this happens.
