33. Sycamore

Reaching 150 feet tall, Sycamore is one of the largest eastern U.S. trees. Due to interlocking grain, its wood is not easily split and is used for tool handles and butcher blocks. After being geographically isolated for 50 million years, Sycamore and the Oriental Planetree (Platanus orientalis) of southeastern Europe were hybridized to give us the London Planetree (Platanus x acerifolia), now a common street tree throughout the temperate world.
