Acacia angustissima

Legume from tropics to prairie

This nitrogen fixer has a wide range, from Belize through Missouri. It is a fairly obscure species here, but in Mexico, where it is called "timbre," it is considered a highly promising tree, valued for nitrogen fixation, coppiced firewood and fodder production, and much more. There is a fair amount of information about it for tropical climates, but these forms must be of Central American origin as they only tolerate minor frosts. Our forms are quite a bit hardier.
