Prosopis alba, commonly known as White Carob Tree, is a deciduous tree native to the Gran Chaco region, which includes dry forests, savannas, and thorn scrub habitats in South America. It typically grows to a height of 5 to 15 meters (16 to 49 feet) with a trunk diameter of up to 1 meter (3.3 feet). The tree has a short trunk and a wide, globular canopy that can reach 10 meters (33 feet) in diameter. The bark is thin, brown-grayish with streaks, and contains tannins. White Carob Tree produces small, greenish-white or yellowish bisexual flowers. The fruits are elongated seedpods, up to 20 cm (7.9 inches) long, containing brown seeds and a sweet, floury paste high in sugar content.

White Carob Tree is valued for its drought tolerance and ability to thrive in arid conditions, making it suitable for xeriscaping. It is used ornamentally for roadside planting and as windbreaks. The tree’s ability to produce abundant fruit, even in years of drought, is a significant benefit. Its sweet pods can be used as fodder or processed into flour for human consumption. In cultivation, it requires full sun, low water, and well-drained soils. However, it can become invasive outside its native range, so gardeners should check local regulations before planting.CC BY-SA 4.0
