About Your New Eucalyptus Microcarpa - Grey Box

Eucalyptus microcarpa, the Grey Box, is a robust medium to large Australian native eucalyptus valued for its drought tolerance, wildlife habitat benefits, and low-maintenance nature. It is a tough, long-lived tree with strong character.

Grey Box grows to 15-25 metres tall with a broad domed canopy spreading 10-15 metres. It has narrow lance-shaped grey-green leaves and a gnarled trunk with rough grey bark. Creamy-white flowers from late summer to autumn attract birds and pollinators. The size and toughness suit shelterbelts, shade planting, and habitat restoration on larger properties.

Grey Box thrives in full sun and well-drained soils, including clay loams and poorer soils, and needs minimal water once established. It performs well across NSW, VIC, and parts of SA, and is valued where longevity and resilience matter more than rapid growth.
