Picea pungens (Glauca Group) 'Koster'
The foliage of Colorado spruce 'Koster' is rigid with silvery-blue prickly needles, rather than in soft plumes like a Chamaecyparis. It is a neat, conical tree, which can take fifty years to reach its full 12m height. Cones are purplish and scaly, forming at the end of shoots.
