Botanical Name: Acacia sophorae
Species: A. sophorae
Common Names: Coastal wattle or Coast wattle
Acacia sophorae is native to Australia – New South Wales, Tasmania, Victoria.
In exposed situations it is a large, prostrate or decumbent shrub, with its trunk and lower branches usually growing along the ground, reaching up to 3 m in height and spreading to 4 m or more horizontally. The oval phyllodes are 50–100 mm long with prominent longitudal veins. The bright yellow flowers occur as elongated spikes up to 50 mm long in the phyllode axils. Flowering occurs mainly in late winter and spring. It occurs on primary dunes, in coastal heath, open forest and alluvial flats. It is used for dune stabilisation on beaches where it will tolerate sea spray and sand blast, providing protection for less hardy plants.
Prefers a sandy loam and a very sunny position. Succeeds in dry soils. Succeeds in any good garden soil that is not excessively limey. Most members of this genus become chlorotic on limey soils. Judging by the plants native habitat, it should tolerate maritime exposure. Trees are not very hardy outdoors in Britain, even in the mildest areas of the country they are likely to be killed in excessively harsh winters. 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.
Seed – cooked. The taste is rather like green peas. Used when green and roasted in the pods, though the pods should not be eaten as these are irritating. 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. Flowers – cooked. Rich in pollen, they are often used in fritters.
Medicinal Uses: Not known to us.
A yellow dye is obtained from the flowers. A green dye is obtained from the seed pods. The extensive root system of this plant helps to prevent soil erosion
