Grevillea robusta Silky Oak

Grevillea robusta, commonly known as the Silky Oak, is a fast-growing, evergreen tree native to Australia. It features fern-like, dark green leaves with a silvery underside and produces striking, golden-orange, toothbrush-shaped flowers in spring and early summer. These blooms attract birds, bees, and other pollinators, adding life to the garden. Growing up to 20–30 meters tall, it’s ideal as a shade tree, windbreak, or for large gardens and rural properties.

To grow Grevillea robusta, plant it in full sun with well-drained soil. It thrives in Melbourne, Sydney, and Brisbane climates, tolerating a range of conditions, including drought, heat, and light frost once established. Water regularly during the first year to promote root development. Minimal maintenance is required, but pruning young trees encourages a strong structure. Avoid phosphorus-heavy fertilizers, as they can harm native plants. *Grevillea robusta* adds elegance and habitat value to any landscape.
