The Agave lechuguilla plant is very salt-water tolerant. The lemon yellow stripe of the Agave lechuguilla plant bisects each leaf margin, which is bounded by a pure white hook and a white tip dagger that is dangerous to the unprotected touch. The spectacular Agave lechuguilla plant grows 1 ft. tall and 2 ft. wide and tolerates 10*F outdoors. Many botanists classify the Agave lechuguilla plant as a hybrid cross of Agave horrida and Agave lopantha.
