The black-spined agave is a small, clumping agave. Blue-grey leaves have black spines along the margins, and form in dense, spherical rosettes. Pups, or baby agaves, will appear near the base of plants. Plants live for approximately ten years, then flower and perish. The pups from the original plant will take over, so the original plant does not need be replaced.
Black-spined agave will tolerate full sun, but it will also appreciate placement under a tree, or anywhere it will receive a bit of afternoon shade. Plant this small agave in a container for an accent, or in a rock garden among colorful desert perennials like desert marigold, angelita daisy, and globe mallow.
