Silky Oak

Scientific name:

Other Names:

Grevillea robusta

Southern Silky Oak, Silk Oak, Silky-Bark Oak, Silver Oak



Silky Oak

Basic info:

An evergreen tree of great beauty. It has stunning golden-orange flowers up to 12cm long. Equally attractive is the foliage of olive-green, fern-like leaves that grow up to 30cm in length.

It grows in riverine, subtropical, and dry rainforest environments and is drought resistant.

Flowering occurs from September to November.

There are 360 species of grevilleas that occur in Australia and Indonesia and are a diverse group. Their colourful, distinctive flowers lack petals and instead consist of a long tube known as a “calyx”, which splits into four “lobes”.

Uses and Interesting Information:

Silky Oaks are older than dinosaurs! They originated on the super-continent Gondwana, and are closely related to banksias, waratahs and proteas.

This particular species of Grevillea IS NOT EDIBLE – DO NOT EAT or place any part of it into your mouth. It is placed here as a wind and shade break and as an associate for the other trees in the orchard.

The word “robusta” refers to the fact that the timber is strong like real oak. The freshly split wood has a silky texture, and a pattern and light colour resembling English oak – hence the common name “silky oak”.

The timber is resistant to wood-rot, and has been widely used in the manufacture of furniture, cabinetry, fences and floors. It has also been used to make guitars due to its tonal and aesthetic qualities.
