About Grevillea acanthifolia A.Cunn.
Grevillea acanthifolia A.Cunn. is an erect or spreading shrub. It typically reaches 0.5 meters (2 feet) in height, though it can sometimes grow up to 3 meters (10 feet) tall and 4 meters (10 feet) wide. Its leaves are 4–9 cm (2–4 in) long and 3–7 cm (1–3 in) wide, with 9 to 14 main lobes; each lobe may be further divided, and ranges from linear to triangular or wedge-shaped, ending in a sharp tip. The leaves themselves are bright green, stiff, and prickly. Flowers are arranged in one-sided, toothbrush-like clusters 3–10 cm (1–4 in) long. The small sepals and petals are pale green to grey, hairy on the outside and glabrous on the inside. The style is 20–28 mm (0.8–1 in) long, red, and tipped with a green pollen presenter. Flowering can occur throughout the year, but peaks between October and February. The fruit that develops after flowering is a hairy follicle marked with reddish patches. This grevillea grows only in New South Wales, most commonly at higher altitudes in wet or boggy habitats. The Grevillea acanthifolia subspecies acanthifolia is cultivated in some gardens, but it is sometimes unreliable when grown at low altitudes. It grows best in full sun and is tolerant of heavy frosts.
