Origin of Name

Obregonia denegrii, commonly known as the Artichoke Cactus, is named after Alvaro Obregon and Mexican botanist F. Negri. The genus Obregonia honors the former President of Mexico, recognizing his contributions to the country, while the species name "denegrii" acknowledges Negri's work in botany.

Technical Description of Plant

Obregonia denegrii is characterized by its unique, artichoke-like appearance, forming a solitary, spherical to slightly elongated stem that resembles a green flower bud. The plant's body is divided into triangular segments, each edged with areoles from which spines emerge. This species rarely grows larger than 10 cm in diameter, making it a compact choice for collectors. The white to slightly pink flowers emerge from the plant's center, adding to its ornamental appeal.

Origin of Plant

Native to the Tamaulipas region of Mexico, Obregonia denegrii thrives in arid desert environments. Its natural habitat is characterized by rocky soils and extreme temperature fluctuations, conditions under which it has adapted to survive by storing water within its dense, succulent stem.

Conservation Status

Obregonia denegrii is listed as a species of concern due to its limited distribution and the pressures of habitat destruction and overcollection. It falls under CITES Appendix I, which restricts international trade of the species to protect it from overexploitation.

Care Instructions

Cultivating Obregonia denegrii requires simulating its natural habitat conditions as closely as possible. It prefers a well-draining cactus mix, bright but indirect light, and infrequent watering to avoid root rot. During the winter months, water sparingly, allowing the soil to dry out completely between watering sessions. It is frost-sensitive and should be protected or brought indoors in climates that experience freezing temperatures. Propagation is typically through seeds, as the plant rarely produces offsets.
