Agave
This agave was found in Scottsdale, Arizona and is of the variety, Agave palmeri. It is native to southern Arizona, southwestern New Mexico, Sonora and Chihuahua. Agave palmeri is the largest species growing in the United States.
Agave is a perennial, but each rosette blooms once and then dies. Some species are known by the name ‘century plant.’
Traditionally, it was circumscribed to be composed of about 166 species, but it is now usually understood to have about 208 species.
Chiefly Mexican, agaves are also native to the southern and western United States and central and tropical South America. They are succulents with 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.
