Grevillearobusta, commonly known as the southern silky oak or silky oak, or Australian silver oak, is the largest species in the genus Grevillea of the family.
Grevillearobusta loves heat and full sun, can take some shade. Best grows with even water distribution during the summer part of the year and has tendency to die back at maturity (age 15-20 years) from prolonged drought stress (more than 4 month) even though seems pretty drought tolerant at younger age.
Adapted to wide variety of soil types, prefers slightly acidic to neutral & can tolerate clay with good drainage. Roots run shallow without drought stress. This quick to grow, rot resistant timber ones was widely used by Australian cabinetmakers as it works easily and has lace-like grain but may cause contact dermatitis.
Silky Oak was introduced widely in temperate regions around the world; it escaped cultivation and became weedy in Hawaii, New Zealand, some parts of India, China and South Africa.
Tree considered an important source of nectar for apiaries, timber, and firewood and leaf mulch.
