Peruvianus

An impressive cactus species native to the Peruvian Andes (where it grows at an altitude of between two thousand to three thousand metres), Trichocereus peruvianus is a short to medium-spined, blue-green and fast-growing columnar cactus which reaches to around six metres tall and produces fabulous white-to-whitish flowers.

The species grows easily outside in USDA Hardiness Zones 8-11, or in most climate zones indoors or under glass. Sow in mildly acidic to mildly alkaline soil, progressing from light shade to full to partial sun as the cacti mature. Transplant into larger containers or the ground after the first year or two. Let the soil totally dry out before watering and fertilise every two weeks to one month over the spring and summer growing season.

Peruvianus forms a complex intergrade with closely-related species including Trichocereus cuzcoensis and Trichocereus macrogonus, loosely comprising an array of great varieties and hybrids. As with many of the well-known South American columnar Trichocereus, peruvianus is often used as a hedge plant, as well as in traditional folk medicine.
