It is often difficult to distinguish between black and white spruce trees. The foliage of the former is darker as a whole, and there are differences in shape and persistence of cones. The names double spruce and single spruce are without evident foundation. Woods exhibit similar qualities and are classed together by lumbermen. Red Spruce (Picea rubens) resembles, and is sometimes considered a variety of, black spruce.
