Description This Colorado Blue spruce cultivar is totally unlike the species in that it forms a rather shapeless plant that sprawls over the ground like a groundcover. The needles are usually a good blue.

  Morphology:
Evergreen prostate tree with horizontal, stiff branches. This variant only grows 6" per year. Once well established this cultivar has a very pleasing growth habit. Leaves are powder blue on limbs that undulate up and down across the ground, with an occasional branch forming a short upright leader.

  Adaptation:
Colorado Blue spruce is a very adaptable tree, surviving and prospering on both moist as well as droughty sites. Best suited to rockery or other site where it can drape over hardscapes.

  Pests:
Spruce aphid and white pine weevil are the usual problems on all spruce cultivars.
