Grevillea baileyana
Brown Silky Oak
The Grevillea baileyana, or Brown Silky Oak, is a medium to tall evergreen tree native to Queensland, Australia, valued for its feathery, dark green foliage and striking yellowish-green flower clusters. Growing up to 15–30 meters tall, it features a straight trunk with rough, brown bark and fern-like leaves that add a tropical touch to gardens and landscapes. During spring and summer, the tree produces large flower panicles that attract birds, bees, and other pollinators.
This hardy, fast-growing tree is ideal for feature planting, shade, or as a backdrop in native or subtropical gardens.
