: In its natural habitat, it typically grows between 10 to 25 meters (33–82 feet) tall. In garden settings, it may remain more compact, often around 5 to 15 meters.
The hallmark "bottle" shape is a slow-developing feature. While the tree itself grows relatively quickly when young, the characteristic swollen trunk typically takes to become noticeable, and up to 15 years to fully mature.
