Swan-neck Agave

Agave attenuata is a species of agave sometimes known as the "lion's tail," "swan's neck," or "foxtail" for its development of a curved stem, unusual among agaves. Native to the plateau of the State of Jalisco in central Mexico, as one of the unarmed agaves, it is popular as an ornamental plant in gardens in many other places. It is reportedly naturalized in Madeira and Libya.
