A cactus with many names
Opuntia cochenillifera, also known as the cochineal cactus or cochineal plant, is a succulent tree in the cactus family Cactaceae. It has passed through several names over its history, having also been classified under Cactus and Nopalea before settling into Opuntia.

A Mexican native, now widespread
This species is native to central, gulf, northeastern, southeastern and southwestern Mexico, where it grows in desert and dry shrubland settings. People have carried it far beyond that home range, and it is now recorded as introduced across a remarkable spread of places, from the Caribbean and parts of South America to India, Southeast Asia, and islands of the Pacific.

A succulent tree habit
Unlike many of its low, sprawling relatives, this Opuntia grows with a tree-like habit rather than staying a compact pad-forming shrub. It belongs to a genus, Opuntia, that is native to the Americas and includes some 185 accepted species, so its tree form sets it apart within a group better known for flatter, paddle-shaped growth.

Uses beyond the pot
Beyond ornamental growing, this species has a working history: it has served as animal fodder, as a medicine, as food for invertebrates, and as a food source for people. That range of uses is part of why it has been moved around the world and now turns up naturalised well outside its native Mexico.
