Picea engelmannii 'Wee Joy' #37 is a dwarf globose selection of Engelmann spruce that, with age, becomes squatly conical, wider than tall. Branching is tight and symmetrical; foliage is of species-typical length, with nice grayish green color. After 10 years, a mature specimen will measure around 30 inches (75 cm) tall and 40 inches (100 cm) wide, an annual growth rate of 2 to 3 inches (5 - 7.5 cm).
This cultivar originated as a natural dwarf tree that was only "30 inches tall, and 50 inches wide, tight, dark green, and very special." These are the words of Colorado's Jerry Morris, who is credited with it'™s discovery and nomination. He first found the tiny tree in the 1980s on Squaw Pass, which is along state highway 103, west of Denver, specifically "up the road to a gate, then uphill."
He first designated it as [#37], meaning that this was Jerry'™s 37th named Engelmann spruce selection, found shortly after P. engelmannii 'Squaw Pass' #36. Nomenclature purists will list this conifer as, Picea engelmannii 'Wee Joy'™ #37.
