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

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

Variations Within Species & 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.
