Species of plant
The succulent, yellow-green rosettes of lechuguilla are 1-2 ft. tall and widely suckering. Thick, leathery leaves are tipped with a strong spine. The lechuguilla, like its relative, the maguey or century plant, requires 12-15 years to store up enough food for the production of the large flower stalk, which then grows amazingly fast up to 15 feet tall. The stalk is unbranched and flexible, so that it often bends when it is heavy with buds or flowers, retaining a permanent, graceful arc. The upper part of the stalk is covered with a solid mass of purplish or yellowish flowers. After producing flowers and seeds, the stalk dies.
This formidable plant was a dangerous obstacle in the early exploration of the Southwest. The sharp leaves pierced horses' legs, and a rider who fell could be impaled. Horses familiar with the country can usually avoid it.
