Silver oak is not an oak at all — it is an Australian tree named for the silvery underside of its fern-like leaves. It is the tree you see shading coffee and tea estates in Coorg, Chikmagalur and the Nilgiris, where pepper vines are often trained up its trunk. Its golden-orange flowers attract birds and bees.
Botanically known as Grevillea robusta, it belongs to the Proteaceae family. It is native to Australia and grows best in a sub-tropical/tropical climate. The parts most often used are the wood and leaves.
