About Agave havardiana Trel.
Agave havardiana Trel. is a plant species native to the Big Bend area of western Texas, United States, and also to the Mexican states of Chihuahua and Coahuila. It grows best on grassy to rocky slopes or in woodlands, at elevations ranging between 1200 and 2000 meters. This acaulescent species forms rosettes that sit low to the ground. It sometimes produces suckers, but unlike some other Agave species, it does not form large colonies. Its leaves can grow up to 70 cm (28 inches) long, and have teeth running along the leaf margins as well as a terminal tooth at the leaf tip. Flowering stalks can reach up to 7 m (23 feet) in height, and bear flowers that range in color from yellow to yellow-green. The fruits it produces are dry, oblong, and can grow up to 6 cm (2.4 inches) long. This species is currently threatened by habitat loss, which occurs primarily to clear land for cattle ranching.
