Agave is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean,[citation needed] although some Agave species are also native to tropical areas of North America, such as Mexico.[citation needed] The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. Agave now includes species formerly placed in a number of other genera, such as Manfreda, ×Mangave, Polianthes and Prochnyanthes.
