The bark on a young tree is grey to reddish-brown, becoming scaly as the tree ages. The cones appear in attractive clumps and are very much like ornaments themselves. The needles are about two centimeters long, and are an attractive dark green or bluish green. The needles of spruce and fir trees are quite similar, but on spruce, the needles are square to round in profile and will roll between your fingers. They are stiff and slightly curved and give off a sharp pungent odour when crushed.
