Agave applanata
An evergreen succulent, forming a stiff rosette of powdery blue-grey leaves, with sharp, slate purple teeth and spines. Young plants have a flattened, spreading form, becoming more upright as they mature, with longer terminal spines. Slow growing, but can reach up to 1.5m high at maturity. Mature plants may produce a tall spike of yellow-green flowers, after which the central rosette dies off
