Story

This tree makes the front of this private property a cool shaded
environment with its spreading canopy.

Chosen and planted by the present owner, along with another of this species in the rear garden, it creates a strong presence in the immediate area and can be seen from a distance along the street.

It is well suited to this confined space. Not common in the Ballan area, though it is common in Melbourne and as a street tree in Albury, due to its modest mature proportions.

Additional Notes

This tree shed a large stem from its upper canopy many years ago; it appears as though it was an acute branch union. The failure impacted the ‘barge board’ at the front of the house and nothing else. The open wound can be seen on the east side of its trunk. There appears to be no fungal decay present in the area of this failure or its lower trunk. This is typical in this species of tree in my experience.
