  • Candicans’- Large bright silver-blue needles on a narrow upright tree.

  • 'Compacta' - lrregularly dwarf compact shrub with bright blue 1 to 11/2” long needles.

  • Violacea’ - silver blue needles of great beauty; might be mistaken for one of the silvery-blue forms of Picea pungens var. glauca.

Unlike the blue spruce, this tree is not susceptible to several problems (including Cytospora canker) that routinely plague the Colorado blue spruce. Plus, the soft foliage is hard to resist every time I walk by one in the landscape.
