Description
Picea pungens Koster Group forms a neat pyramidal evergreen with dense tiers of mostly horizontal branches and vivid silvery-blue needles. Its year-round color and strong outline make it a natural focal tree for a spacious sunny garden.
Grow it in moist but well-drained acidic or neutral soil, with room for the crown to broaden. Water young trees consistently and stake grafted plants until a straight leader develops. Established trees tolerate dry periods. The stiff needle tips can cause puncture injuries, so wear gloves when handling branches.
