About

Grevillea pteridifolia is a species of flowering plant in the family Proteaceae and is endemic to northern Australia. It is also known by many common names, including golden grevillea, silky grevillea, fern-leaved grevillea, golden parrot tree, golden tree, manbulu, yawuny and tjummula. It is a shrub or tree usually with pinnatisect leaves, and bright orange-yellow or reddish flowers.

How to grow it

Golden grevillea grows readily in warm climates, generally preferring extra water in summer and well-drained soils. The brittle branches can break in strong winds. Several popular garden grevilleas are hybrids between Grevillea pteridifolia and other species. Grevillea 'Sandra Gordon' is the result of crossing with G. sessilis. Grevillea 'Honey Gem' is a cross with a red form of Grevillea banksii. Similar to 'Honey Gem' is G. 'Winter Sparkles', another hybrid of G. pteridifolia and G. banksii.

The leaves were used as stuffing and as a herb when cooking emu by the Aborigines on Groote Eylandt, and used by early settlers to stuff pillows.

Where it grows

Grevillea pteridifolia is found from the Kimberley region of Western Australia, across the Northern Territory and into Queensland where it is found along the Great Dividing Range to the vicinity of Barcaldine. It is found in regions with wet summers, dry winters and 500 to 1,500 mm (20 to 59 in) annual rainfall.
