How to identify a sycamore tree
Look for peeling bark.
The bark of a sycamore tree is brittle and can't withstand the rapid growth that sycamores experience. So the bark peels off frequently, and this results in a patchy, flaky appearance.

Choose your answer from:
- Another common find is flakes or debris on the bark. It could be caused by bark oils, fall pollen, even junk mail..
- Search for " camouflage " colors in the bark. Because the older bark peels off and reveals younger bark beneath, the bark of sycamores will be a variety of colors-brown, green, tan, and white..
- Appreciate knots, clamps, and roots. The bark and its surrounding leaves can all be knots, and actually make the tree healthier overall..
- Particularly ripe sycamores should not have any visible signs of rot that might indicate disease. The bark of the tree also should be firm to the touch, and a golden color..
The answer is:
Search for " camouflage " colors in the bark. Because the older bark peels off and reveals younger bark beneath, the bark of sycamores will be a variety of colors-brown, green, tan, and white.
