The range of the Havard agave, agave havardiana, is limited, to northwest Mexico and far west Texas - primarily in the Big Bend area (in particular the Chisos Mountains), and the Davis Mountains. Plants form open rosettes, formed of stout, thick leaves, colored greyish-green; relatively few in number compared to some other species. Leaves are up to 24 inches long and 10 inches across, remaining broad until just past the middle, then tapering to a brownish grey spine. The purplish edge teeth are about a third of an inch in length, and somewhat irregular in orientation.
This species inhabits quite high elevations, up to 6,500 feet, from open grassland to oak or pinyon-juniper woodland, and can tolerate low temperatures, down to -20°F. It may form hybrids with agave lechuguilla.
