Echinocactus grusonii, commonly called Mother-In-Law's Cushion or Golden Barrel Cactus, is a barrel cactus endemic only to the east-central area of Mexico. This is a cactus that makes a bold statement in any xeric or desert garden, and is very popular in desert landscapes.
!t is critically endangered in its native range, and may reach over 3 feet high. This cactus is desert grown and is accustomed to a 10+ UV index from intense sunlight, and will not burn. Cactus that burns in desert environments is a common problem with many cacti offered in the big box garden centers.
This species requires full sun, soil that drains very well, and after established, occasional watering keeps it happy.
