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. See photo. If you have it, enjoy it. Culture should be similar to V. farnesiana.
Attracts pollinators and uses ants both for protection against unwanted insects.
|Native Habitats:||Coastal uplands, ruderal, shell middens|
Distribution and Planting Zones
Natural Range in Florida
Suitable to grow in:
10A 10B 11 8B 9A 9B
USDA zones are based on minimum winter temperatures
|Ethnobotany:||In southern Europe this species is extensively planted for the flowers, which are a perfume ingredient.|
|General Comments:||Although drought-tolerant, this shrub/small tree may benefit from a few deep, thorough soakings during extremely dry periods. When young, it tends to be multi-trunked, so if a tree form is desired, pruning is required. Very briefly deciduous. Although the range extends further north, it is best used in landscaping where temperatures do not drop below 20 degrees F.|
