What actually happens is that the leaves follow the sun, and by Newton’s third law this imparts a twisting motion to the tree in the opposite direction, and over the years the tree screws itself into the ground, so these trees have very deep support systems. If you transplant one to the northern hemisphere, it twists in the opposite direction, unscrewing itself instead, and eventually it unscrews itself completely and falls over. Transferring anything between hemispheres can have disastrous consequences of this sort. My wife is Australian and ever since she came to the northern hemisphere she gets left and right confused much of the time. HTH – Derek

Death to the warped and twisted eucalyptus!! Sara, who has personally been responsible for the murder of twenty such evil tree-beings. Tree-huggers, please sit on your hands.
