This is a very cold-hardy Agave, growing to an imposing 30 x 36ins wide when mature in its native habitat, the Davis Mountains of west Texas USA where they have cold winters but very hot baking summers. Its massive, thick, bluish-grey leathery leaves have vicious spines, so keep away from pathways!
It takes low temperatures exceedingly well if planted on gravely well drained sandy soils, or raised up on a rockery. In high rainfall areas it should have a cover in the winter to stop rain getting in the crown. It makes an excellent container plant that can then be protected from winter rains.
