The Colorado Blue spruce) (Picea pungens glauca) , is a variety of the Colorado Spruce, is a medium to large, narrow, pyramidal conifer with horizontal branching to the ground. The foliage can vary from green to bright powder blue which can be attributed to a thicker-than-normal waxy coating on the true-green needles, refracting sunlight and reflecting it back to the human eye in a blue wavelength.
