4-5’x4-6’ wide. (Also known as Agave macroculmis.)This huge, montane species is native to high elevations (7,000 to 9,000 ft.) in the Sierra Madre Mountains of NE Mexico. The large, wide leaves are gray-green in color and fiercely spined along leaf margins and at the tip. This is a relatively fast growing species that needs extra water in low desert regions.
