Swamp Gum

Eucalyptus ovata

Lowland Leadbeater’s Possum and Helmeted Honeyeater feed on the flowers of this species, which flowers at a different time from the Mountain Swamp Gum. This overlap of flowering time provides food across an extended period for these creatures.

Small to medium tree, 20 m tall. Bark is variable, dark and rough at the butt; upper trunk and branches peel in ribbons.


Juvenile leaves are short-stalked, almost circular. Adult leaves are thick, glossy, dark green, ovate shaped, usually has a wavy edge.


White cluster of 3 - 10 (often 7).


Usually cone-shaped with a flat top.
