Eucalyptus cosmophylla

Common Name:
Cup Gum

Description:
Eucalyptus cosmophylla, commonly known as Cup Gum, is a small to medium-sized Australian native tree valued for its attractive form, textured bark, and suitability to a range of landscape settings. It features rough, fibrous bark on the trunk and lower branches, contrasting with smoother upper limbs, creating visual interest throughout the year. The foliage consists of dull green to grey-green leaves that form a moderately dense canopy, providing light shade. In summer, it produces clusters of creamy white flowers that attract birds, bees, and other pollinators. Well suited to Melbourne conditions, Cup Gum thrives in full sun and prefers well-drained soils, particularly sandy or loamy types, but can tolerate poorer soils once established. It is drought tolerant and relatively low maintenance, making it ideal for use as a feature tree, in native plantings, or for revegetation projects. Its moderate size makes it more suitable for suburban gardens compared to larger eucalyptus species.
