Cleistocactus Strausii Houseplant - Wooly torch Cactus

Meet the Cleistocactus strausii (Wooly torch Cactus)

Cleistocactus strausii, commonly known as the Silver Torch Cactus, is native to the high-altitude regions of north-western Argentina and southern Bolivia. It grows naturally on rocky mountain slopes and arid valleys in the Andes, where conditions are harsh—intense sun, cool nights, and very little rainfall. To cope with this environment, the plant developed its dense covering of silvery-white spines, which help protect it from strong sunlight and sudden temperature drops. First described in the late 19th century, Cleistocactus strausii has since become a popular ornamental cactus worldwide, valued for its striking upright form and dramatic appearance.
