The Agave most commonly called the 'Century Plant'. There are numerous forms, but the typical form is a fairly giant grower reaching 6 to 10 feet across in a rosette of wide, tapering, stiff leaves with prominent marginal spines and terminating in a elongated, sharp, stiff terminal spine. The plants are attractive with a gray, gray-green or glaucous coloration. Size is somewhat dependent on container size, and those planted in landscape will attain the maximum size. Very stately and widely used in landscapes world wide. Many plantlets or offsets are produced on stolons around the base for easy propagation. The inflorescence can reach 30 feet tall, after which the plant dies off. Grown all over the world, but native only to Mexico.
