About Eucalyptus polyanthemos - Red Box

Eucalyptus polyanthemos, commonly known as Red Box, is a resilient and striking Australian native tree celebrated for its dense canopy, textured fibrous bark, and unique blue-grey foliage. Growing 10–15 metres tall and spreading 6–10 metres wide, this medium-sized evergreen tree brings both structure and soothing colour to a wide range of landscapes—from native habitat gardens to contemporary rural settings.

Its standout feature is the foliage, with soft, rounded juvenile leaves giving way to elliptical, silver-blue adult leaves that contrast beautifully with natural elements like stone or timber. Creamy-white flower clusters appear in spring to early summer, attracting bees, birds, and other pollinators, adding life and movement to your outdoor space.

Thriving in full sun and adapting to most well-drained soils, Red Box is highly drought-tolerant once established and requires minimal maintenance. Its rough, grey to brown bark adds texture and character year-round. Best suited to spacious areas, this tree excels as a feature specimen, habitat garden addition, rural windbreak, or streetscape tree.

It looks excellent in natural and designed landscapes alike, offering enduring beauty and native charm with effortless care—ideal for anyone seeking a dependable and elegant evergreen native tree.
