Neltuma alba (algarrobo blanco) is a medium-sized, dry-climate tree from South America, typically 5 to 15 m tall with a short trunk and a broad, rounded crown. It needs full sun and very little water, so it suits hot, dry sites rather than wet or humid gardens.

About
Neltuma alba (formerly Prosopis alba) is a South American tree species that grows in central Argentina, the Gran Chaco ecoregion, and part of the Argentine Mesopotamia, as well as Bolivia, Chile, Paraguay, and Peru. It is known as algarrobo blanco ('white carob tree' or "white algarrobo") in Spanish. Spanish settlers gave it that name because of its similarity to the European carob tree (Ceratonia siliqua). Other common names come from Guaraní, including ibopé and igopé.
Neltuma alba is a medium-sized tree, measuring between 5 and 15 m (16 and 49 ft), in height and 1 m (3.3 ft) in diameter, though such tall specimens occur very rarely at present. The trunk is short and the treetop is globular, sometimes reaching 10 m (33 ft) in diameter. The bark is thin, brown-grayish in colour, with streaks, and it has tanning properties.
