Agave lechuguilla

Agave lechuguilla (common name in Chihuahua: "lechuguilla", meaning "small lettuce") is an "Agave" species found only in the Chihuahuan Desert, where it is an indicator species. It typically grows on calcareous soils. The plant flowers once in its life and then dies. The flowers are a source of nutrients for insects, bats, and some birds.
The leaves are long, tough, and rigid, with very sharp, hard points that can easily penetrate clothing and even leather, giving the colloquial name "shin-daggers". Mexican people have used fibers from the leaves (commonly called "ixtle")."
The water stored in the flowering stalks of this plant, rich in salts and minerals, is sold in Mexico as a sport drink. The plant makes up a large part of the diet of the collared peccary (SW USA: javelina) in some areas. It is toxic to cattle and sheep, however. Roots of the plants were used as soap by Native Americans.
The plant reproduces most often through underground offshoots, creating large colonies. It also can flower at any time after the plant has reached three to 21 years of age, producing a leafless stalk that can reach in height. The flower clusters are located at the top and are funnel-shaped in purples, reds, and yellows. The plant dies after flowering.
Charles Wright first collected the plant in 1849 and it was described by John Torrey in 1859.
