Agave parryi, Parry's Agave, is native to the Southwest United States and Mexico. Glaucous gray leaves in basal rosettes will reach 1 foot tall (30cm) and about 4 inches wide (10cm). The succulent leaves end with a brown to gray terminal spine 1 inch (2.5 cm) long (very rigid and sharp) and bear sharp small-recurved spines on the margins. It is one of the cold hardiest of the agaves and will grow in drier areas of USDA zones 5-11.
Blooming Time: The inflorescence is about 15 feet (5 meters) tall with creamy yellow flowers.
Culture: Agave parryi need full sun and a well-drained soil. We use a soil mix consisting of equal parts of loam and sand with small gravel added to increase drainage. The plants can withstand a lot of drought and still look good. We water ours twice a month in the greenhouse and fertilize once during the growing season. During the winter months we drop the temperatures to 50° F (10° C) and water only enough to keep the leaves from shriveling.
Propagation: Agave parryi are propagated by removal of offshoots from the base in spring.
