Golden Barrel Cactus

The Golden Barrel Cactus, scientifically known as Echinocactus grusonii, is one of the most iconic and universally recognized cactus species, celebrated for its perfect spherical form and striking golden spination. Native to the volcanic rocky hillsides of central Mexico, particularly the states of Hidalgo and Querétaro, it thrives in hot, arid to semi-arid climates with excellent drainage, often found growing in groups. As a long-lived perennial, this magnificent cactus can live for over 30 years and potentially much longer in ideal conditions, developing into a substantial and venerable specimen.

Its most defining characteristic is its perfectly spherical shape when young, gradually elongating into a more barrel or columnar form as it matures, reaching diameters of up to 3 feet and heights of 3 feet or more. The stem is a vibrant bright green, heavily ribbed with numerous, sharply defined vertical ribs. Each rib is densely covered with numerous areoles from which emerge brilliant, stiff, and exceptionally sharp golden-yellow spines, giving the entire plant a shimmering, golden glow that truly lives up to its name. In late spring to summer, mature specimens (typically those over 1 foot in diameter) produce a ring of small, waxy, bright yellow flowers around the crown, at the very top of the cactus. These blooms are followed by small, fuzzy, whitish fruits. The Golden Barrel Cactus is an extremely popular choice for xeriscaping, rock gardens, desert landscapes, and large container plantings, highly prized for its bold architectural form, brilliant coloration, and exceptional drought tolerance.
