Agave cupreata 'Gray Form' (Gray Dwarf Cowhorn) A medium sized non-suckering Agave that grows to 1 to 2 feet tall by 2 to 3 feet wide with broad gray-green leaves that have dark copper-colored spines on large mammilate protrusions (teats) along the slightly wavy margins. The dark teeth contrast well with the light gray-green leaves that also display well the bud imprinting that occurs when the leaves press up against the margins of the newer leaves in the center of the plant. This species has been aptly described as looking like a larger green Agave colorata or a smaller Agave bovicornuta but this particular form is much grayer than typical Agave cupreata. It is a beautiful garden plant and is suitable for container gardening. The species occurs naturally in the Mexican state of Guerrero and Michoacán where it grows on mountain slopes from 4,000-6,000 feet in the Río Balsas basin. Plant in full sun in a well-drained soil. Irrigate little (if at all) to occasionally. Mostly listed as hardy to around 28° F but can go a little colder - large plants in Goleta California were not damaged at 26° F in January 2007. Our plants are a selection from seedling plants that we noted were much grayer than typical Agave cupreata. The seed was provided to us by John Bleck. The specific epithet comes from the Latin word 'cupre' meaning "copper" in reference to the copper colored spines of this species.  The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have observed it in. We also will incorporate comments received from others and always appreciate getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that might aid others in growing Agave cupreata 'Gray Form'.
