Most Edible Acacia seed species are from northern semi-arid regions of Australia and range from medium-sized trees to large, multi-stemmed bushes.  Several Edible Acacia species have been successfully introduced into African semi-arid regions like Niger and Senegal.

A. tumida has grown well in Niger but needs slightly higher rainfall conditions to thrive; the tree may grow rapidly, but fail to set seed.  It has large seeds which are easy to harvest and better balanced nutritionally than A. colei seed.
