Blue spruce

Blue spruce is a medium-sized evergreen tree growing to 25–30 m tall, exceptionally to 46 m tall, and with a trunk diameter of up to 1.5 m . The bark is thin and gray, with narrow vertical furrows. The crown is conic in young trees, becoming cylindric in older trees. The shoots are stout, orange-brown, usually glabrous, and with prominent pulvini.

Picea pungens (Colorado Blue Spruce or Blue Spruce) is a species of spruce native to western North America, from southeast Idaho and southwest Wyoming, south through Utah and Colorado to Arizona and New Mexico. It grows at high altitudes from 1,750-3,000 m altitude, though unlike Engelmann Spruce in the same area, it does not reach the alpine tree-line. It is most commonly found growing along streamsides in mountain valleys, where moisture levels in the soil are greater than the often low rainfall in the area would suggest. More
