Platanus occidentalis
Platanaceae
Sycamore

Sycamore (Platanus spp.), also known as buttonwood or plane, is composed of five to nine species which grow in Eurasia [2] and North America [8]. All species look alike microscopically. The common name “sycamore” is used in England to designate a species in the hard maple group (Acer pseudoplatanus), whereas plane or planetree is used to name the Platanus that grows there. The word platanus is the classical Latin and Greek name of Platanus orientalis L., oriental planetree, from the Greek word for broad, referring to the leaves.

Distribution: The eastern United States, from the Canadian border to the Gulf of Mexico and from the Atlantic coast west to the Great Plains.

The Tree: Sycamore trees reach heights of 120 ft (37 m), with a diameter of 3 ft (1 m).

General Wood Characteristics: The sapwood of sycamore is white to light yellow, while the heartwood is light to dark brown. The wood is classified as moderate in weight, hardness, stiffness, shock resistance, strength in bending, endwise compression and nail-holding ability. It has a close texture, glues well, and resists splitting due to interlocked grain. Sycamore is odorless, stain-free, and tasteless.

Working Properties: Sycamore has a close texture, glues well, and resists splitting because of its interlocked grain. It holds its shape well after steaming and machines well, but requires high speed cutter heads to prevent chipping.

Durability: Rated as nonresistant to heartwood decay.

Preservation: No information available at this time.

Uses: Furniture (especially drawer sides), containers, millwork, flooring, veneer, pallets, boxes, plywood, pulp wood, paper, particleboard.

Toxicity: No information available at this time.
