About

Neltuma chilensis (formerly Prosopis chilensis) is a species of tree in the family Fabaceae. It is found in parts of central Chile, southern Peru, Bolivia, and Andean (northwestern) Argentina. Its common names include Chilean mesquite (algarrobo chileno, in Spanish), cupesí (in eastern Bolivia), and Chilean algarrobo. It is used for providing shade, for animal feed, and firewood.

Where it grows

Neltuma chilensis is found in Peru, Bolivia, eastern Argentina, and central Chile, growing on light soils in arid regions. It is highly drought-resistant and likely fixes nitrogen. It has been introduced into Hawaii, where it is now commonly found growing in thickets behind beaches.

Uses

Neltuma chilensis is used as a shade tree and for firewood. The leaves are used as fodder for livestock and the pods and seeds are of high nutritive value and are ground to make an animal feed. Honey bees, and several other species of bee, pollinate the flowers.
