Sycamore bark is very distinctive. The multi-coloured patches are unique.

The bark on very old trees is quite different! However, the characteristic patchy bark will still be visible on younger branches farther up in the tree.

Typical Sycamore leaf. Sycamores are late leafers. In June their leaves are still growing out.

The fruit of Sycamore are these balls, about 1-2" in diameter.

They often persist on the tree through the winter, eventually breaking apart into fine fibers which readily blow about in the wind.
