Agave attenuata is a native to the plateau of the State of Jalisco in central Mexico. This agave is now rare in the wild.
Agave attenuata forms rosettes (>1.2m) of succulent-like, soft fleshy, lime green to bluish, 60cm, leaves. The leaves have no teeth on their margins, nor any terminal spines.
Some of its common names relate to the plant's development of an unusually curved raceme(inflorescence). This dense arching raceme can grow up to 7 m in length and has creamy coloured flowers. It may take up to 10 years for the Agave attenuata to bloom (although this varies with the location of the plant). After flowering the plant dies and suckers from the new plant will form at the bottom of the old plant.
