Butternut

Color/Appearance: Heartwood is usually a light to medium tan, sometimes with a reddish tint. Growth rings are darker and form fairly distinct grain patterns. Sapwood is a pale yellowish white.

Grain/Texture: Grain is typically straight, with a medium to coarse texture. Silky natural luster.

Endgrain: Semi-ring-porous; medium-large earlywood pores gradually decreasing to small latewood pores; solitary and radial multiples of 2-3; tyloses occasionally to abundantly present; growth rings distinct; rays barely visible without lens; parenchyma banded (marginal), apotracheal parenchyma diffuse-in-aggregates (sometimes very faint and barely visible even with lens).

Rot Resistance: Decay resistance is rated as moderately durable to non-durable.; also susceptible to insect attack.

Workability: Butternut is easily worked with both hand and machine tools. However, being so soft, Butternut has a tendency to leave some fuzzy surfaces after planing or sanding, and sharp cutters and fine-grit sandpaper is recommended. Butternut glues, stains, and finishes well.

Odor: Butternut has virtually no scent or odor when being worked.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Veneer, carving, furniture, interior trim, boxes, and crates.

Comments: Sometimes called White Walnut, Butternut is indeed closely related to Black Walnut. While the difference is not black and white, the wood of Butternut is considerably lighter-colored than Black Walnut, as well as being very soft and lightweight.

Butternut trees can be distinguished from Black Walnut by looking at its fruit: Butternut’s fruit is more oblong or oval shaped, while Walnut is nearly round; (see illustration below). The commercial potential of Butternut’s edible fruit (nuts) is generally regarded as being more valuable than its lumber. (Butternuts are not related to Butternut squash, which comes from an unrelated plant—Cucurbita moschata.)

The trunks of Butternut trees are fluted, which is sometimes still evident in processed lumber—the growth rings in the endgrain may appear more polygonal and faceted rather than perfectly circular.
