- Common Names
- Pecan
- Scientific Name
- Carya illinoinensis
- Origin
- South-central United States and Mexico
- Appearance
- Heartwood tends to be light to medium brown, with a reddish hue; sapwood is a paler yellowish brown. Grain is usually straight, though occasionally wavy. Texture is medium, with a low natural luster. Endgrain: Ring-porous to semi-ring-porous; large to very large earlywood pores in a single intermittent row, medium to small latewood pores solitary and radial multiples of 2-3, few; tyloses common; parenchyma reticulate (bands absent from earlywood row in true hickory group, but present in pecan hickory group); narrow rays, close spacing.

- Durability
- Considered to be non-durable to perishable regarding heartwood decay, and also very susceptible to insect attack.
- Workability
- Difficult to work, with tearout being common during machining operations if cutting edges are not kept sharp; the wood tends to blunt cutting edges. Glues, stains, and finishes well. Responds well to steam bending.
