The grey gum tree, Eucalytus punctata, is native to South East Queensland where I live. It can grow as tall as 35 metres. I have a few of these trees on my acreage property.
The trunk of the grey gum has patchy colours of white and grey, with orange patches showing new bark.
The fruit of a gum tree is called a gum nut.
The old bark peels off in long ribbons and is often seen caught in tree forks. There is usually a large pile of shed bark around the base of the trunk.
The flowers provide a food source for nectar eating birds and possums as well as the grey headed flying fox. The leaves on the grey gum are also a tasty treat for koalas.
This particular grey gum has lots of scratches of different sizes on the trunk, from the base all the way up the tree as far as I could see. Koalas? Possums? Goannas? The tree obviously gets plenty of use.
Gum trees shed their bark once a year.
