20 Seeds Silky Oak Grevillea robusta Fast Growing Evergreen Flowering Tree

Silky Oak is a fast growing evergreen tree known for its fern like foliage and large golden orange flower clusters. Grevillea robusta adds a tall, graceful structure to landscapes and is widely grown as a shade tree, screen, or specimen in frost free climates. Its finely divided leaves and distinctive flowering display give it a soft, feathery appearance all season.

The luminous flowers are ornamental and held in showy upright racemes that attract nectar feeding birds when in bloom. The ferny leaves and upright habit also make it useful as a background planting or windbreak in suitable regions. Grow it where it has room to develop its tall, single trunked form and enjoy the textural contrast it brings to a mixed planting.
