The Details

Eucalyptus Microcarpa - Grey Box Profile

Eucalyptus microcarpa, known as Grey Box, is a robust medium to large native eucalyptus highly valued for its drought tolerance, habitat benefits, and low-maintenance nature. Growing 15–25 meters tall with a broad domed canopy spreading 10–15 meters, this evergreen tree features narrow lance-shaped grey-green leaves and a gnarled trunk with rough grey bark, offering both character and resilience.

Ideal for full sun locations, Grey Box thrives in well-drained soils, including clay loams and poorer soils, and requires minimal water once established. Its creamy-white flowers from late summer to autumn attract birds and pollinators, enhancing biodiversity in rural and urban landscapes alike. This tree looks excellent when used as a shelterbelt, shade tree, or for habitat restoration, especially where longevity and toughness are prized over rapid growth. It’s a powerful, elegant choice that stands strong in harsh conditions while adding natural beauty and ecological value.

Plant Spacing Recommendations

Hedging & Screening: Not typical.

Feature Tree: 5 m – 6 m apart to show its spreading habit.

Avenue Planting Trees: 6 m – 8 m apart.
