Australian Silver-oak.. or Silky-oak…

Grevillea robusta, commonly known as the southern silky oak or Silky-oak, or Australian Silver-oak.

It’s a native of Australia, it’s a fast growing evergreen tree, between 18–35 m tall with dark green delicately dented bipinnatifid leaves similar in a way to a fern frond. It is the largest plant in the Grevillea genus, and it can reach a diameter in excess of one metre. The leaves are generally 15–30 cm long with greyish white or rusty undersides. Its flowers are golden-orange bottlebrush-like blooms, between 8–15 cm long in the spring, situated on a 2–3 cm long stem and are used for honey production.

The timber from this tree was widely used for external window joinery as it is resistant to rotting. It was also popular for making furniture.

The flowers and fruit contain toxic hydrogen cyanide.

A tree is flowering at the moment and I took a few close ups of the flower and one can see the sweet nectar on the blooms…
