The thorny branches make good cover for birds and other wildlife. Fruits are not generally valued. Attracts pollinators.

There are 2 subspecies, V. farnesiana var. farnesiana and V. farnesiana var. pinetorum.  Var. pinetorum is rare.  It is also smaller.

There is a very rare species, Vachellia macranthera, occasionally cultivated.  It occurs rarely in extreme south Florida and has been found as a likely storm-deposited waif in a couple of areas on the west coast of FL.   If you have it, enjoy it.  Culture should be similar to V. farnesiana.

Attracts pollinators and uses ants both for protection against unwanted insects.
