Accepted Scientific Name:
Echinocactus grusonii
Origin and Habitat
Echinocactus grusonii, widely known as the Golden Barrel Cactus, originates from the central Mexican states of Hidalgo and Zacatecas. It naturally occurs on arid, rocky slopes and volcanic hillsides, often at altitudes of 1,000 to 1,400 meters. This cactus is adapted to hot, dry climates with infrequent rainfall and high sunlight exposure. Due to habitat destruction and limited natural range, it is now rare in the wild and classified as endangered, although it remains popular in cultivation.
Description
The Golden Barrel Cactus forms a nearly perfect spherical shape, growing up to 36 inches in diameter and reaching a height of 24 inches. Its body is deeply ribbed and lined with dense, golden-yellow spines that give the plant its iconic appearance. In mature specimens, small yellow funnel-shaped flowers may emerge in summer at the crown, typically only under full sun conditions.
