Hollow sycamores can still lead long lives.
Age and Changes
As a sycamores mature, the brown, gray and green bark on their lower trunk peels in patches. The colorful patches contrast with the white inner bark , forming a colorful mosaic. When sycamores get to be 200 years old, their sapwood no longer transfers minerals and water from their roots. Resins and tree wastes collect and harden in the heartwood or core of the tree. This heartwood frequently rots, but hollow sycamores can still lead long lives.
