Common name: Silver oak, Silk oak • Manipuri: কৌবীলিযা Koubilia • Bengali: ৰূপসী Rupasi • Tamil: சவுக்கு மரம் Savukku-maram
Botanical name: Grevillea robusta     Family: Proteaceae (Silver oak family)

Reaching a height of 75 feet or more with a 25-foot spread, Silver Oak is pyramidal to oval in shape, eventually developing a few heavy horizontal limbs and a thick trunk. It is a fast growing evergreen tree, between 18-35 m tall with dark green delicately dented bipinnatifid leaves reminiscent of a fern frond. These leaves are generally 15-30 cm long with silvery undersides. Its flowers are golden-orange bottlebrush-like blooms, between 8-15 cm long, in the spring, on a 2-3 cm long stem. A great quantity of leaves fall in the spring immediately preceding the emergence of new growth and leaves also fall sporadically throughout the year, creating quite a litter problem to some people. Black, leathery seed capsules follow the flowers.
