Picea abies 'Dubois' / Dubois Norway spruce

Picea abies 'Dubois' is a dwarf, globose cultivar of Norway spruce with symmetrical, albeit somewhat clumpy branches and radially arranged, glossy medium green needles. After 10 years of growth, a mature specimen will measure 12 inches (30 cm) tall and wide, an annual growth rate of around 1 inch (3 cm).

It is not known whether or not this cultivar every gained much traction in the nursery trade. It's origin is speculative at best. A fine, mature specimen lives in Bickelhaupt Arboretum in Clinton Iowa. By its appearance, one can assume that is was a witch's broom selection. Dubois is a town is west-central Pennsylvania, where the broom was possibly found. Joe Stupka of Pulaski was the foremost broom hunter from that area and is probably the finder.
