Peruvian torch cactus (Echinopsis peruviana)
Description
Echinopsis peruviana (syn. Trichocereus peruvianus), the Peruvian torch cactus, is a fast-growing columnar cactus native to the western slope of the Andes in Peru, between about 2,000–3,000 m (6,600–9,800 ft) above sea level. It contains the psychoactive alkaloid mescaline as well as other alkaloids, although reported levels vary considerably and do not approach the concentrations found in Echinopsis pachanoi. The plant is bluish-green in color, with frosted stems, and 6-9 broadly rounded ribs; it has large, white flowers. It can grow up to 3–6 m (9.8–19.7 ft) tall, with stems up to 8–18 cm (3.1–7.1 in) in diameter; it is fully erect to begin with, but later possibly arching over, or even becoming prostrate. Groups of 6-8 honey-colored to brown rigid spines, up to 4 cm (1.6 in) in length, with most about 1 cm (0.39 in), are located at the nodes, which are evenly spaced along the ribs, up to approximately 2.5 cm (0.98 in) apart.
