Eucalyptus microcarpa

Eucalyptus microcarpa (Grey Box)

Eucalyptus microcarpa, commonly known as Grey Box, is a durable and long‑lived eucalypt native to the woodlands and plains of south‑eastern Australia. It is recognised for its thick, fibrous grey bark that persists along the trunk and larger branches, and its narrow, grey‑green adult leaves that give the tree a soft, muted appearance in the landscape. Small clusters of creamy white flowers appear seasonally, followed by woody, cup‑shaped fruit. This species typically grows 10–25 metres, forming a rounded to spreading crown with strong structure.
