Obregonia is a genus with one species, Obregonia denegrii, the artichoke cactus, a slow-growing, small globular cactus from Mexico. It is rare and endangered in the wild, so grow only plants from nursery-propagated stock.
Obregonia, the artichoke cactus, is a monotypic genus of cacti, containing the species Obregonia denegrii. The species is endemic to the state of Tamaulipas in Mexico.
The genus Obregonia is named after Álvaro Obregón, while the species is named after Ramon P. De Negri, who was the Minister of Agriculture of Mexico when the cactus was first described by Alfred Frec in 1923.
Obregonia denegrii originates from the Valley of Jaumave in Ciudad Victoria, Tamaulipas, Mexico, commonly thriving at elevations around 1000 meters. This plant prospers in semi-desert open areas and dense bushes. It grows slowly in culture and requires little water. It benefits from full sun and is multiplied by seed. It is very slow growing.
The Nahuatl Indians call the plant peyotl, and it is said to have hallucinogenic alkaloids. It is one of the closest living relatives of the genus Lophophora.
