This is a F. obliqua I collected growing out of a sandstone wall in Rushcutters Bay, Sydney, around 20+ years ago. It had a canopy about 3ft across, and these 2 slender trunks holding the whole mass up. No idea how old it is but it must have been growing in the crack in the wall for at least 10 yrs or so to get to the size it was.??? I removed all the branches at the time and ran a saw against the wall and base cut it free. It now stands around 15ins tall and 16in wide canopy. The nebari is my biggest issue with this tree…. very one sided due to its original growing angle. Never really known how to correct or improve it, so have learned to live and work with it.
