Sclerocactus polyancistrus in cultur B

Sclerocactus polyancistrus, commonly known as the Hedgehog Cactus, is a species of cactus native to the southwestern United States and northwestern Mexico. This plant is particularly noted for its distinctive appearance, characterized by a spherical to cylindrical shape, dense spination, and vibrant flowers that bloom in the spring.

Description

Sclerocactus polyancistrus grows to a height of 10 to 30 cm and a diameter of 6 to 15 cm. The plant's body is green, covered with white to gray spines that can become dense enough to obscure the cactus flesh. The spines are arranged in radial and central patterns, providing the cactus with a formidable defense against herbivores.

The flowers of Sclerocactus polyancistrus are notable for their beauty, ranging in color from pink to magenta, and occasionally white. They appear at the top of the cactus in the late spring and can last for several days. Following the flowering period, the plant produces small, greenish fruits that later dry and release seeds.

Habitat and Distribution

Sclerocactus polyancistrus is found in the desert regions of the southwestern United States, particularly in Nevada, Utah, and Arizona, as well as in northwestern Mexico. It thrives in arid environments, on rocky slopes, and in sandy plains, often at elevations from 600 to 2,400 meters above sea level.

Conservation

The species is considered to be of least concern by conservation authorities; however, it faces threats from habitat destruction, illegal collection, and the impacts of climate change. Efforts to conserve Sclerocactus polyancistrus include habitat protection and the regulation of cactus trade.

Cultivation

In cultivation, Sclerocactus polyancistrus is valued for its unique appearance and relatively easy care. It requires a well-draining soil mix, minimal water, and full sunlight. It is frost-tolerant to a degree but should be protected from extreme cold. Propagation is typically done through seeds, as the plant rarely produces offsets.
