The Celtis Tree is also known as Hackberry or Sugarberry migrated from the Northern hemisphere and appears in garden beds all around Sydney. This tree produces thousands of seeds which are rapidly spread by birds. Small saplings grow with such vigor that before you know it you have a large tree in your backyard which requires an arborist and his tree removal crew to remove.
Shown is a picture of a 30 metre Celtis tree which was growing out of a garden bed in Lindfield. The tree was growing out and over the neighbours pool and had to be removed in limb by limb. The neighbour was ecstatic that the tree was removed and the seeds had stopped falling onto their property.
