Agave, from the Greek word αγαυή, meaning “noble” or “admirable,” is a common perennial desert succulent, with thick fleshy leaves and sharp thorns. Agave plants evolved originally in Mexico, but are also found today in the hot, arid, and semi-arid drylands of Central America, the Southwestern U.S., South America, Africa, Oceana, and Asia. Agaves are best known for producing textiles (henequen and sisal) from its fibrous leaves, syrup sweeteners, inulin (a food additive), and alcoholic beverages, tequila, pulque, and mescal, from its sizeable stem or piña, pet food supplements and building materials from its fiber, and bio-ethanol from the bagasse or leftover pulp after the piña is distilled.

Agave’s several hundred different varieties are found growing on approximately 20% of the earth’s surface, often growing in the same desertified, degraded cropland or rangeland areas as nitrogen-fixing, deep-rooted trees or shrubs such as mesquite, acacia, or leucaena. Agaves can tolerate intense heat and will readily grow in drylands or semi-desert landscapes where there is a minimum annual rainfall of approximately 10 inches or 250 mm, and can survive temperatures of 14 degrees Fahrenheit (minus 10 degrees Celsius).
