Barrel Cactus
Echinocactus grusonii
The Barrel Cactus (Echinocactus grusonii) is one of the most iconic desert plants, known for its bold spherical shape, vertical ribbing, and golden-yellow spines. Native to Mexico, it thrives in dry, sunny environments and brings a strong visual element to succulent arrangements, rock gardens, or sunny windowsills.
Though it looks intimidating, the Barrel Cactus is incredibly easy to care for — requiring very little water, minimal humidity, and lots of sunlight. Its sculptural form makes it a favorite among collectors and modern interior stylists.
It may produce yellow flowers in summer when grown outdoors, but this is rare in indoor conditions.
