Giant Barrel Cactus Seeds

The largest of all barrel cacti is native to the deserts of northeastern and central Mexico and can reach a height of up to 15 feet, with a diameter of 4 feet or more. It grows relatively slowly and forms a deeply ribbed, dark green stem armed with short brown spines. It does best in dry, warm temperate climates in USDA Zones 10 to 11 and should be kept as dry as possible during winter.
