Picea pungens (Blue spruce): Cones
		The hanging cones are 2 to 4 inches long and cylindrical, tapering at the ends. The pale, shiny-brown cone scales are flexible, with blunt, jaggedly-toothed margins at the apex. Good seed crops are produced every 3 to 4 years, the dark brown seeds having wedge-shaped wings twice the length of the seed.
