Uses

"Acacia longifolia" is widely cultivated in subtropical regions of the world. Its uses include prevention of soil erosion, food, yellow dye, green dye and wood. The flower colour derives from the organic compound kaempferol. The tree's bark has limited use in tanning, primarily for sheepskin. It is useful for securing uninhabited sand in coastal areas, primarily where there are not too many hard frosts. In Tasmania the ripening pods were roasted and the seeds removed and eaten.
