Description

Grevillea formosa is a sprawling shrub that typically grows to a height of up to 1 m (3 ft 3 in), with trailing branches up to 2 m (6 ft 7 in) long. Its leaves are divided, 60–180 mm (2.4–7.1 in) long with 5 to 26 erect, linear leaflets, sometimes further divided, the end lobes 30–90 mm (1.2–3.5 in) long and 0.5–1.0 mm (0.020–0.039 in) wide. The edges of the leaflets are rolled under, but are not sharply-pointed. The flowers are arranged in toothbrush-like clusters along a rachis 120–300 mm (4.7–11.8 in) long. The flowers are green, turning bright golden-yellow as they age, the pistil 54–60 mm (2.1–2.4 in) long. Flowering occurs from January to March and the fruit is a shaggy-hairy follicle 11–16 mm (0.43–0.63 in) long.[2][3]
