They are native to the arid, mountainous regions of South Bolivia to North Argentina and grow between 10,000-15,000ft above sea level. The long, white hairs protect them from both light frost and intense UV rays. As they mature plants will assume a clumping habit and produce new stems that will emerge from the soil. A versatile cactus, they can be grown as a houseplant, on the patio, in containers or in the ground. Just make sure to provide sufficient light to indoor plants.
