PLANT PROFILE

Eucalyptus spathulata, commonly known as the Swamp Mallet, is a striking Western Australian native tree known for its smooth, glossy bark and dense, fine-textured canopy. The trunk and branches are often coppery-bronze to dark grey in colour, shedding annually to reveal a satiny surface. The narrow, bright green leaves form a tidy, rounded canopy, and small clusters of white flowers appear from late winter to spring, attracting birds and pollinators. Mature trees typically reach 6–10 metres tall with a spread of 4–6 metres, forming an upright, compact shape suited to open landscapes or street plantings.

This hardy evergreen species thrives in full sun and well-drained soils, particularly sandy or gravelly types. Eucalyptus spathulata is drought and frost tolerant once established and performs exceptionally well in exposed, coastal, and low-rainfall areas. It’s a fast-growing, low-maintenance tree that provides both ornamental appeal and environmental value through habitat and shade.

They look excellent as feature trees in native or Mediterranean-style gardens, planted in avenues, or used for windbreaks and habitat restoration. With its attractive bark, tidy form, and resilience, the Swamp Mallet is a versatile choice for both urban and rural landscapes.
