18" x 18-30" wide, (seed propagated). An incredible non-suckering selection of Parry's Century Plant, the seed for our crop was collected on a brutally cold, exposed high-altitude plateau (6,800' elevation) south of Flagstaff in Coconino Co., Arizona. The silver-gray plants are growing in a clay-loam soil mixed with black volcanic boulders. Without question, this is one of the largest, most cold-hardy forms of Agave you can grow. Plant in a lean, well-drained soil where it will get plenty of sun and heat. In time, the plant will bloom with a towering 12' tall, flowering candelabra that will attract hummingbirds from miles around. Zones 4 -10. #1 Gallon pot size.
