WOOD FLOORINGS - Walnut

Walnut Juglans Nigra Availability: Moderately available, normally in unfinished parquet, strip and in various plank widths as a special order. Available in fancy parquet patterns as a special order or custom mill.

COLOR: Heartwood ranges from a deep, rich dark brown to purplish black. Sapwood is nearly white to tan. Difference between heartwood and sapwood color is great; some flooring manufacturers steam lumber to bleed to darker heartwood color into the sapwood, resulting in a more uniform color.

GRAIN: Mostly straight and open, but some boards have burled or curly grain. Arrangement of pores is similar to hickories and persimmon, but pores are smaller in size.

VARIATIONS WITHIN SPECIES AND GRADES: Great variety of color and figure within species, as well as variation in color among boards, especially in lower grades and from material that isn't steamed prior to kiln-drying.
