Two other species, G. baileyana and G. glauca, occur in both New Guinea and Queensland.

Uses

Traditional Aboriginal use

Grevillea flowers were a traditional favourite among Aborigines for their sweet nectar. This could be shaken onto the hand to enjoy, or into a coolamon with a little water to make a sweet drink. They might be referred to as the original "bush lollies".

Cultivation

New Holland Honeyeater on Grevillea aspleniifolia, Australian National Botanic Gardens, Canberra

Many species are cultivated for their distinctive foliage and showy flowers, and they have been extensively hybridised. They can be grown from soft tip cuttings from December-March (in the Southern Hemisphere) or seed.

Many harder to grow species can be grafted onto hardy rootstock such as Grevillea robusta.

Grevilleas hybridise extremely easily in cultivation. this has resulted in a huge number of named Grevillea cultivars.

They are also good bird-attracting plants, honeyeaters in particular are common visitors. They are also used as food plants by the larvae of some Lepidoptera species including the Dryandra Moth.

There is an active Grevillea Study Group in ASGAP for people interested in Grevilleas, both for uses in horticulture and for conservation in the wild.
