Heartwood

The dense, mature inner wood of a tree trunk that is no longer actively conducting water. Heartwood is typically darker, harder, and more decay-resistant than the outer sapwood. In cabinetry, heartwood and sapwood color differences create natural variation in wood components — particularly noticeable in species like cherry, walnut, and hickory. Some homeowners request all-heartwood selection for consistent color.
