Grevillea banksii is an erect, bushy shrub or slender tree from eastern Queensland, grown for its distinctive red or cream flowers. It is one of the most widely cultivated grevilleas and a parent of many garden hybrids.
Grevillea banksii, commonly known as Banks' grevillea, Byfield waratah, red flowered silky oak and dwarf silky oak, and in Hawaii as kāhili flower, is a species of flowering plant in the family Proteaceae and is endemic to Queensland. It is an erect shrub or slender tree with divided leaves with four to twelve narrow lobes, and creamy white to bright scarlet and yellow flowers.
Grevillea banksii is one of the most widely cultivated grevilleas and is a parent of hybrids including G. 'Robyn Gordon' and G. 'Superb', G. 'Moonlight', G. 'Misty Pink', G. 'Pink Surprise', and G. 'Ned Kelly'.
The flowers and seed pods contain toxic hydrogen cyanide. The alkyl resorcinols in G. banksii and Grevillea 'Robyn Gordon' are responsible for contact dermatitis.
Banks' grevillea is mostly found on the Queensland coast from Ipswich to Yeppoon, but sometimes further inland. It mostly grows in woodland and forest, usually in flatter places.
