The term “Echinocactus” is derived from the Greek words “echinos,” meaning hedgehog or sea urchin, and “cactus,” referring to the cactus plant. This genus name is aptly chosen as Echinocactus species typically have a spherical or barrel-shaped appearance with prominent ribs and spines, resembling the spiky characteristics of a hedgehog or sea urchin.

Commonly known as the barrel cacti, echinocactus enhance landscapes with ornamental beauty, making them popular for gardens and xeriscaping. They thrive in full sunlight with well-draining soil, preferably a cactus mix. Keep them in warm, arid climates, protecting from frost. Water sparingly, allowing soil to dry between watering. Fertilize modestly during the growing season, and ensure good air circulation to prevent fungal issues.
