Acacia elongata is a large shrub growing to 3 m or a bit taller by 1.5 m wide in sunny damp situations in NSW. It is usually found in sandstone and sandy woodlands and heath. Grows mainly along the NSW coast and tablelands subdivisions but also extends into the western slopes.
The phyllodes are linear and very narrow in shape, to about 13 cm long by about 0.3 cm wide with prominent longitudinal veins and ending in a short point. Dark green and somewhat curved.
The flowers are produced in globular heads. Each head may contain up to 42 very small staminate flowers. Each head is to 1 cm in diameter.
Flowers are yellow to bright yellow in colour. Flowering is mainly in late winter and spring, July to October.
The heads are then arranged in racemes of up to 7 but usually only 1 to 3, in the axils of the phyllodes.
Pods are straight and flat but raised over seeds to 11 cm long and to 0.5 cm wide.
A. elongata is a versatile plant that is frost hardy (will tolerate frosts to -7°C) is resistant to salt spray and will grow in damp and poorly drained situations.
Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these occurring.
Propagation is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.
Most wattles regenerate from seed after fire.
Acacia – from Greek akis, meaing a thorn or “thorny”.
