About

Senegalia berlandieri (Berlandier acacia, guajillo acacia, guajillo, huajillo, huajilla) is a shrub native to the Southwestern United States and northeast Mexico that belongs to the Mimosoid clade of Fabaceae. It grows 1 to 5 metres (3.3 to 16.4 ft) tall, with blossoms that are spherical and white, occurring from February through April. The berlandieri epithet comes from the name of Jean-Louis Berlandier, a French naturalist who studied wildlife native to Texas and Mexico. S. berlandieri contains a wide variety of alkaloids and has been known to cause toxic reactions in domestic animals such as goats.

Uses

Senegalia berlandieri is toxic to livestock and thus should not be used as forage or fodder.
