    Nursery contributed plant descriptions

    Wow! This behemoth of an Agave is truly one of the most impressive garden plants one can grow. Its monster rosette of grey green leaves with hefty spines produces occasional offsets. Ultimately reaching dimensions of 12' wide or more, it needs a large space and should be surrounded by plants of similar scale not to be an overwhelming figure in the cactus garden. Hardiness reports vary anywhere from about 5 °F on up to 20 °F - this may owe to differences in provenance or to the possibility that many plants considered to be this species are actually a form of A. protamericana, which is much hardier. But if you don't want to risk it, it's still an impressive container specimen, and produces plenty of offsets which can be saved as insurance against a cold winter.

    By: Kara Nursery

    Huge, scary agave, to 4-6' tall x 6-12' wide over time, with an urn-shaped silhouette made up of foot wide, gray leaves. Originating in Mexico, these are common as accents in gardens with Mediterranean climates, as they rarely flower. Sun, good drainage, and very little summer water is necessary. Cold hardy in USDA zone 9, to 20-25 °F. Good for containers.
