Picea engelmannii 'Stanley Mountain' / Stanley Mountain Engelmann spruce

Picea engelmannii 'Stanley Mountain' #28 is a compact, upright, conical dwarf selection of Engelmann spruce with attractive, bright, sky-Blue needles. After 10 years of growth, a mature specimen will measure 36 to 40 inches (90 - 100 cm) tall and somewhat wider, an annual growth rate of around 3 to 4 inches inches (7.5 - 10 cm).

This cultivar originated as a witch's broom found in the 1980s by Colorado's Jerry Morris. He found the original broom on 3th hairpin curve, on the east side of Berthoud Pass which is along state highway 40, due west of Denver. Jerry described it as, "4 feet tall and wide, tight, and Blue.

He first designated it as [#28], meaning that this was Jerry’s 28th named Engelmann spruce selection. Nomenclature purists will list this conifer as, Picea engelmannii ‘Stanley Mountain’ #37.
