The Echinocactus grusonii is native to the arid regions of central Mexico, specifically the state of Querétaro.

Unfortunately, its natural habitat has been significantly impacted by human activities, including dam construction, leading to its endangered status in the wild.

Physical Characteristics

The Golden Barrel Cactus is renowned for its globe-shaped form, which can reach impressive sizes in mature specimens.

Its body is characterized by prominent ribs that run vertically along its surface, lined with numerous areoles.

Mature plants, given the right conditions, produce yellow flowers, that emerge from the crown of the plant.

The growth rate of this cactus is very slow.
