Silver oak

Grevillea robusta, commonly known as the southern silky oak or Silky-oak, or Australian Silver-oak, is the largest species in the genus Grevillea. It is a native of eastern coastal Australia, in riverine, subtropical and dry rainforest environments receiving more than 1,000 mm per year of average rainfall. It is a fast growing evergreen tree, between 18–35 m tall with dark green delicately dented bipinnatifid leaves reminiscent of a fern frond. It is the largest plant in the Grevillea genus, reaching diameters in excess of one metre. The leaves are generally 15–30 cm long with greyish white or rusty undersides. Its flowers are golden-orange bottlebrush-like blooms, between 8–15 cm long, in the spring, on a 2–3 cm long stem and are used for honey production. The seeds mature in late winter to early spring, fruiting on dark brown leathery dehiscent follicles, about 2 cm long, with one or two flat, winged seeds.
