A medium to large tree native to northern Australia, Indonesia, and Papua New Guinea with attractive, sickle-shaped phyllodes (leaves that are actually not leaves but widened leaf stalks) and yellow, bottle-brush-like flowers in great profusion.
Besides being grown as an ornamental it also makes good firewood, charcoal and pulp and yields tannins and gum that are commercially exploited. The wood is also used for furniture and other purposes. Germination: Scarify seeds. Soak for 24 hours. Sow seeds about 1/4 inch apart in a seed tray. Cover the seeds lightly with soil (about the depth of a seed), lightly press down the soil and water. Place above ground level in a warm, humid, partly-shaded area. Keep the soil moist but not wet. Germination takes 1-4 weeks.
