Stetsonia coryne
Toothpick cactus (Stetsonia coryne) is the only species in its genus, a large tree-like cactus from the dry Gran Chaco region of South America. It needs full sun, very well-drained soil and sparing water, and it grows too large for most homes.
Stetsonia coryne, the toothpick cactus, is the sole species in the cactus genus Stetsonia. Stetsonia coryne is native to arid regions of South America, where it grows to a height of 15 to 25 ft (4.6 to 7.6 m) tall. It contains mescaline and other alkaloids.
Stetsonia coryne is distributed in high-altitude arid regions, such as the deserts and dry forest (Gran Chaco) of northwestern Argentina, as well as in Bolivia, Paraguay, and the Brazilian state of Mato Grosso do Sul.
