Yellow poplar trees grow taller than any other U.S. hardwood species and they are members of the magnolia family. The bark, leaves, flowers, fruit and roots contain pharmaceuticals. Poplar is the state tree of Indiana, Kentucky and Tennessee.

Where It Grows

Widespread throughout Eastern U.S. Tree heights can reach 150 feet.

Main uses

Light construction, furniture, kitchen cabinets, doors, musical instruments, exterior trim and siding, paneling, mouldings and millwork, edge-glued panels, turnings and carvings.

Relative Abundance

11.2 percent of total U.S. hardwoods commercially available.

Did You Know?

The poplar tree is rarely attacked by parasites.

General Description

The sapwood is creamy white and may be streaked, with the heartwood varying from pale yellowish brown to olive green. The green color in the heartwood will tend to darken on exposure to light and turn brown. The wood has a medium to fine texture and is straight-grained; has a comparatively uniform texture.

Working Properties

A versatile wood that is easy to machine, plane, turn, glue and bore. It dries easily with minimal movement in performance and has little tendency to split when nailed. It takes and holds paint, enamel and stain exceptionally well.

Physical Properties

A medium density wood with low bending, shock resistance, stiffness and compression values, with a medium steam-bending classification. Excellent strength and stability.

Availability

Very widely available.

a) Results of tests on small clear specimens in the green and air-dried conditions. Definition of properties; impact bending is height of drop that causes complete failure, using 0.71-kg (50 lb.) hammer; compression parallel to grain is also called maximum crushing strength; compression perpendicular to grain is fiber stress at proportional limit; shear is maximum shearing strength; tension is maximum tensile strength; and side hardness is hardness measured when load is perpendicular to grain.

b) Specific gravity is based on weight when ovendry and volume when green or at 12% moisture content

c) Modulus of elasticity measured from a simply supported, center-loaded beam, on a span depth ratio of 14/1. To correct for shear reflection, the modulus can be increased by 10%.
