The mighty Fabaceae (pea) family contains the genus Acacia which consists of five genera – Acacia, Vachellia, Senegalia, Acaciella, and Mariosousa. In 2005, the International Botanical Congress voted to reclassify many acacias. While the entire genus consists of more than 1,200 sub-species, only 160 species of shrubs and trees exist in the acacia.

This genus sprouted up in subtropical and tropical areas, especially in areas of Africa and Australia. Also known as wattles, they form landmarks on the savanna and the veld.

The Acacias trees and shrubs resemble large ferns due to their leaves. These leafstalks contain numerous leaves of leaflets with tiny, small divisions. This causes the leafstalk to take on the appearance of a big, green feather or a fern. Some Pacific and Australian species feature flattened leafstalks with no leaflets or suppressed leaflets. These small branches grow vertically with prickles in a curved shape or thorns at the base.

Of course, acacias also bear pungent flowers in circular clusters. These globs of small white or yellow flowers contain multiple stamens producing a fuzzy look to the plant. Acacias bear fruit that qualifies as legumes.

The genus Acacia provides a diverse, massive range of species from Mulga and myall to grass wattles. The former dominates in arid regions, the latter in moist environments. Australian Acacia typically features a modified, flattened leaf axis of a compound leaf. They can lose all their leaflets. These plants bear radially symmetric flowers.

Frequently Asked Questions

In what environments do acacia grow well?

Acacia trees love warmth. They developed in areas of the world that tend to experience higher temperatures. The harsh environments limit their growth, so most varieties are either shrubs or small trees. A few varieties only grow to a height of a few inches. These pod-bearing, thorny plants feature the fluffy round sweet blossoms of yellow or white.

What area of the world has the most acacia?

Australia sprouted up the most natural varieties – about 300 species. In its earliest settlements, the residents used the plant’s branches to make their huts called wattle-and-daub. The early settlers called them wattles because they used the plant branches to make wattle-and-daub huts. To this day, an acacia, the golden wattle, is Australia’s national tree.
