Agave is a succulent plant of a large botanical genus of the same name, belonging to the family Agavaceae. Chiefly Mexican, agaves occur also in the southern and western United States and in central and tropical South America. The plants have a large rosette of thick fleshy leaves, each ending generally in a sharp point and with a spiny margin; the stout stem is usually short, the leaves apparently springing from the root. Along with plants from the related genus Yucca, various Agave species are popular ornamental plants.
