Seed - roasted. Starchy. Rather small and fiddly to gather[K]. Acacia seeds are highly nutritious and contain approx 26% protein, 26% available carbohydrate, 32% fibre and 9% fat. The fat content is higher than most legumes with the aril providing the bulk of fatty acids present. These fatty acids are largely unsaturated which is a distinct health advantage although it presents storage problems as such fats readily oxidise. The mean total carbohydrate content of 55.8 + 13.7% is lower than that of lentils, but higher than that of soybeans while the mean fibre content of 32.3 + 14.3% is higher than that of other legumes such as lentils with a level of 11.7%. The energy content is high in all species tested, averaging 1480+270 kJ per 100g. Wattle seeds are low glycaemic index foods. The starch is digested and absorbed very slowly, producing a small, but sustained rise in blood glucose and so delaying the onset of exhaustion in prolonged exercise.Seedpods - roasted. The pods are up to 10cm long.
A green dye is obtained from the seed pods. The extensive root system of this plant helps to prevent soil erosion. It is used on sandy soils and steep banks. Trees are planted as a screen in Australia. This species is often grown as a rootstock for grafting lime-intolerant members of the genus.Wood - pale, tough.

Hardy to about -10°c for short periods, it can be grown outdoors in many of the milder areas of the country though, even in Cornwall, it is liable to be cut back to the ground in excessively cold winters. It can resprout from the base. Tasmanian provenances are the hardiest forms in British gardens. Dislikes root disturbance. A very ornamental plant. The flowers are scented of violets.This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby.
