Silky Oak (Grevillea robusta)

The name “Silky Oak” is given to a number of different genera and species in Australia, but it originally referred to Grevillea robusta.
Grevillea robusta is a deciduous tree which can reach up to 35 m (115 ft) in height, though it is most likely to be 25 m (80 ft) or less. It has fern like green leaves and attractive golden flowers. Grevillea robusta is one of the best nectar producers. Its sweet nectar attracts insects, birds and marsupials.

The plant has been used for the manufacture of furniture, interior woodwork, cabinetry, decorative veneers, fences, gunstocks and guitars.
The wood was traditionally referred to as “Lacewood” in its native Australia. The term “Lacewood” is used to describe any wood produced from a number of different wood species, such as Cardwellia sublimis, Lagetta lagetto, Platanus occidentalis, Roupala montana and Grevillea robusta.
