This form, known as the White Barrel, is from a restricted area in Queretaro, Mexico. Uncommon, the white form of Echinocactus grusonii is a very distinctive landscape species, although it has less frost tolerance than does the better-known typical species. We’ve grown this in the ground for many years with no problems, but these plants do have some rib damage from past frosts that you have to look closely to see. The plants should grow out of this minimal damage. These plants are seedlings in 6-inch pots.
