Often regarded as one of the best cultivars, Thomsen blue spruce is a medium-sized pyramidal evergreen conifer native to the southern Rocky Mountains in the western United States; it was selected in 1928. The pungent needles are bright steel blue (to almost white-blue) and are thick, creating a very picturesque texture. Grasp these thick needles and you'll be unpleasantly prickled. The mature form is a handsome pyramid, but with a neat stature. It is a slow-growing plant.
The desirable Thomsen blue spruce grows its finest in full sun and well-drained fertile soil. A moist fertile soil is ideal, but it can withstand many stresses, including drought, pollution, salt and wind. Use it as a specimen in a lawn, or as a tall screen or windbreak.
