Reliably winter hardy to USDA Zones 7-10. Best growth occurs in a sandy/gritty, dry to medium moisture, well-drained soil in full sun. Tolerates some light shade. Sharp soil drainage is important. Poorly-drained soils inevitably lead to root rot. Tolerates dry soils and drought. Surprisingly good winter hardiness for this succulent. Plants have reportedly survived winters with temperatures as low as -20F (USDA Zone 5), but cold temperatures should be "dry cold" as opposed to "wet cold". Agave parryi, often called Parry’s agave or mescal, is a rosette-forming perennial succulent that is native to grasslands, chaparral, desert scrub, pinyon-juniper and oak woodlands in Arizona, New Mexico and northern Mexico typically at elevations from 4,000 to 8,000 feet.
