American Sycamore Tree Seeds (Platanus occidentalis) 50+Seeds Zones 4-9
An American sycamore tree is easily recognized by its mottled exfoliating bark. It is said that the sycamore had gotten its name because from its exfoliating bark; it looks 'sick'. The bark of all trees has to yield to a growing trunk; in the case of trees such as the Silver Maple and the Shagbark Hickory the process is not hidden, but the Sycamore shows the process of exfoliation more openly than any other tree. The bark of the trunk and larger limbs flakes off in great irregular masses, leaving the surface mottled, and greenish-white, gray and brown.Sometimes the smaller limbs look as if whitewashed. The explanation is found in the rigid texture of the bark tissue, which lacks the elasticity common to the bark of 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.
