Flat Top Acasia Overview

Vachellia abyssinica was previously know as Acasia abyssinica. Its species were considered members of genus Acacia until 2005. Vachellia can be distinguished from other Acacias by its capitate inflorescences and spinescent stipules. The tree has a flat crown with beautiful flaky bark. The bark on young trees is yellowish and it fades to red/brown on older trees. The twigs are hairy and the thorns are paired and straight. It's a lovely shade tree with edible gum. It enriches the soil as it fixes nitrogen in the soil. A useful tree for bee farmers. This tree has many uses and although the wood is not durable, it is used to carve crafts, instrument handles, utensils and for firewood.
