American Sycamore Tree

Platanus occidentalis

Description:

The hollow trunk growth caught my attention. Hole was four feet tall. An American sycamore tree can often be easily distinguished from other trees by its mottled exfoliating bark, which flakes off in great irregular masses, leaving the surface mottled, and greenish-white, gray and brown. The bark of all trees has to yield to a growing trunk by stretching, splitting, or infilling; the Sycamore shows the process more openly than many other trees. The explanation is found in the rigid texture of the bark tissue, which lacks the elasticity of the bark of some other trees, so it is incapable of stretching to accommodate the growth of the wood underneath and the tree sloughs it off. A sycamore can grow to massive proportions, typically reaching up to 30 to 40 meters (98 to 130 ft) high and 1.5 to 2 meters (4.9 to 6.6 ft) in diameter when grown in deep soils. The largest of the species have been measured to 51 meters (167 ft), and nearly 4 meters (13 ft) in diameter. Larger specimens were recorded in historical times. In 1770, near the junction of the Kanawha and Ohio Rivers, George Washington recorded in his journal a sycamore measuring nearly 45 feet (14 m) in circumference at 3 feet (91 cm) from the ground. The sycamore tree is often divided near the ground into several secondary trunks, very free from branches. Spreading limbs at the top make an irregular, open head. Roots are fibrous. The trunks of large trees are often hollow. Another peculiarity is the way the leaves grow sticky, green buds. In early August, most trees in general will have—nestled in the axils of their leaves—the tiny forming bud which will produce the leaves of the coming year. The sycamore branch apparently has no such buds. Instead there is an enlargement of the petiole which encloses the bud in a tight-fitting case at the base of the petiole.

Habitat:

On the grounds of Buckeye Furnace. A restored iron furnace in southeastern Ohio.
