Echinoagave

Echinoagave is a genus of flowering plants in the family Asparagaceae. It includes 12 species native to Mexico. The species in genus Echinoagave were formerly placed in genus Agave, and both genera share a rosette habit and terminal spine. Echinoagave species are distinguished by their generally compact hedgehog-like shape, with cylindrical to subcylindrical to flattened leaves with hard, firm, striate-sulcate and serrulate margins. Echinoagave plants are typically polycarpic, flowering multiple times before dying, in contrast to the typically monocarpic Agave species whose rosettes die after flowering....read more on Wikipedia.
