Interesting Facts

Acacia is indigenous to warm regions like Mexico and Australia. They attract birds and work well in multiple climates. They are generally used in landscaping. Acacia seeds are often used for seasoning food and drinks, and are listed as ingredients in Barq's root beer and Altoids mints. The species Bullhorn acacia lacks the bitter alkaloids usually located in the leaves that defend against insects and animals. Bullhorn acacia ants fulfill that role. They lives in its hollowed out thorns at the base of their leaves and protect the tree and in exchange live off the protein rich nodules (Beltian bodies) and nectar from the glands on its leaf stalk. There is no other known function of these Beltian bodies than to feed the ants. The aggressive ants release an alarm pheromone that livestock smell and avoid. The ants will also "prune" seedlings around it to prevent them from block out sunlight, which the Acacia's need to survive.

Plant Care
Planting:

Few nurseries carry more than just a handful of Acacia species, but they are easily propagated via self collected seed. They can also be grown from cuttings and grafting.

Plant Growth:

Acacias are native to warm regions of the world and do best with full sun. Size varies depending on the variety. The shortest, Acacia redolens, generally varies between 1' and 6' tall, with a spread of up to 15'. The tallest variety, Acacia koa, can reach heights and spreads of up to 60'.

Blooming:

Flowers form in early to midwinter and some species have very fragrant flowers.

Soil and Irrigation:

They require little to no water, and will basically grow in any soil that is not too wet.

Pruning:

Acacia can form either shrubs or trees, depending on their pruning treatments during early life. To produce a more shrub-like plant, remove the lead shoot. For a more tree-like plant, prune lower branches. Regardless, branch density should be thinned out and pruned back to the trunk to prevent dieback of innermost branches and protect against wind damage.

Pests:

Pest infestation and damage is rarely a problem.
