Agave 'Blue Brian'

Cactus Succulent Conservatory Greenhouse

A slow-growing evergreen succulent, forming a stiff rosette of broad, dark green leaves with a powdery blue-grey bloom. Leaves have sharp teeth along the edges and spines at the tip, and often show patterned bud imprints. Mature plants may produce a tall spike of yellow flowers, after which the central rosette dies off, to be replaced by new offsets produced at the base
