The term eastern spruce includes three species: red (Picea rubens), white (P. glauca), and black (P. mariana). White and black spruce grow principally in the Great Lake States and New England, and red spruce grows in New England and the Appalachian Mountains.
The wood is light in color, and there is little difference between heartwood and sapwood. All three species have about the same properties, and they are not distinguished from each other in commerce. The wood dries easily and is stable after drying, is moderately lightweight and easily worked, has moderate shrinkage, and is moderately strong, stiff, tough, and hard.
The greatest use of eastern spruce is for pulpwood. Eastern spruce lumber is used for framing material, general millwork, boxes and crates, and piano sounding boards.
