The needles are single, angular or four-sided, yellow-green in color, 1/2 to 1 inch long and slightly curved.  More of the needles are borne on the upper surface of the twigs where they usually point forward. The foliage appears to droop or weep.

The cone is 4 to 7 inches long; light brown; hanging down.  Norway spruce grow 75 to 100 feet tall. They make good winter cover for wildlife.
