About Tristaniopsis laurina – Water Gum

Tristaniopsis laurina, commonly known as the Water Gum, is a small to medium-sized Australian native tree valued for its compact form and attractive foliage. It develops smooth, mottled bark in shades of grey, cream, and orange, creating year-round visual interest. The leaves are glossy green, lance-shaped, and arranged densely along the branches, providing a neat, rounded canopy. In summer, clusters of small, yellow, star-shaped flowers appear, followed by woody seed capsules. Mature specimens generally reach 7–12 metres tall with a spread of 4–7 metres.

This species grows at a moderate rate and is well adapted to a wide range of soils, including those prone to occasional wetness. Tristaniopsis laurina is evergreen, hardy, and tolerant of light frost once established. It performs best in full sun to part shade and is low-maintenance, requiring only occasional pruning to shape when young. The flowers are nectar-rich, attracting birds, bees, and other pollinators.

They look excellent when planted as feature trees in gardens, used for avenue or street plantings, or incorporated into parks and civic landscapes. Their manageable size, neat form, and reliability make them popular in both residential and public planting schemes.
