Echinocactus
Echinocactus is a genus of slow-growing, globular to barrel-shaped cacti native to arid regions of Mexico and the southwestern United States. Characterized by their ribbed bodies, prominent spines, and woolly crowns, these cacti are highly adapted to harsh desert environments. The most well-known species, Echinocactus grusonii, commonly called the Golden Barrel Cactus, is prized for its striking appearance and drought tolerance. Echinocactus species produce yellow, funnel-shaped flowers at the plant’s apex, typically in mature specimens. They thrive in full sun, require well-draining soil with pumice, and prefer infrequent watering to prevent root rot.
