Echinocactus grusonii is a well known species of cactus native to central Mexico from San Luis Potosi to Hidalgo.
Described by Heinrich Hildmann in 1891, it is popularly known as the Golden Barrel Cactus, Golden Ball or, amusingly, Mother-in-Law's Cushion. It belongs to the small genus Echinocactus, which together with the related genus Ferocactus, are commonly referred to as barrel cacti.
Despite being one of the most popular cacti in cultivation, it is rare and critically endangered in the wild.
Growing as a large roughly spherical globe, it may eventually reach over a meter in height after many years.
