Acacia complanata A.Cunn. ex Benth.

Shrub or tree to 5 m high; branches arching downwards. Branchlets ±flexuose, flattened, narrowly winged, glabrous. Phyllodes often patent, narrowly elliptic, mostly 5–10 (–12.5) cm long and 10–30 (–45) mm wide, obtuse to subacute, thinly coriaceous, glabrous, with 7–9 prominent distant main veins and openly reticulate in between; pulvinus 2–3 mm long. Inflorescences 4–8 per axil in axillary fascicle or sometimes fascicles racemose on axis to 30 mm long; peduncles 8–12 mm long, glabrous; heads globular, ± 6 mm diam., 35–45 (–60)-flowered, bright yellow. Flowers 5-merous; sepals free to ½-united. Pods linear, rounded over seeds alternately on each side and shallowly to moderately constricted between them, to 15 cm long, 6–10 mm wide, thinly coriaceous-crustaceous, wrinkled ±reticulately over seeds, glabrous. Seeds longitudinal, subglobular, 4–5 mm long, dull, dark brown; funicle encircling seed.

A subtropical species. It is adaptable to most soils and conditions. It is drought and frost resistant. It suits warmer places but can be grown in cooler places. It does best with a well drained soil and in a sunny position. It suits hardiness zones 9-11.

The seeds are edible.

It is grown from seed. The seed needs to be treated to break the hard seed coat. Normally this is by putting the seeds in very hot water and letting the water cool down overnight then planting the seeds immediately. Plants can be pruned to stop them becoming thin and straggly.
