Description
editGrevillea × gaudichaudii is a naturally occurring hybrid between Grevillea acanthifolia subsp. acanthifolia and Grevillea laurifolia, growing as a prostrate plant 2–3 m (6 ft 7 in – 9 ft 10 in) in diameter. Its leaves are pinnately-lobed, the lobes oblong to egg-shaped and softly-hairy on the lower surface but not sharply pointed. The flowers are arranged in toothbrush-like racemes less than 25 mm (0.98 in) long and are dark pink to burgundy-red, the style more than 20 mm (0.79 in) long and the ovary stalked and glabrous. Flowering occurs from October to December.[2][3][4]
Taxonomy
editGrevillea × gaudichaudii was first formally described in 1827 by Charles Gaudichaud-Beaupré in Voyage autour du monde, entrepris par ordre du roi from an unpublished description by Robert Brown of plants collected in the Jamieson Valley (near Katoomba).[5][6]
Distribution and habitat
editThis grevillea grows in sandy soil and is restricted to parts of the higher Blue Mountains.[4][7]
Use in horticulture
editA fast-growing ground cover, this grevillea is frost-resistant and tolerates most soil types, preferring sunny sites in well-drained soil. It can be grown from cuttings.[3][8]
