Picea abies 'Horace Wilson' is a diminutive, cushion-like selection of Norway spruce with dense, layered branching and short, medium green needles. After 10 years, a mature specimen will measure 10 inches (25 cm) wide and 6 inches (15 cm) high, an annual growth rate of less than one inch (2.5 cm).
This cultivar originated as a witch's broom found by Horace Wilson of Mentor Heights Nursery, Mentor, Ohio on a specimen of Picea abies 'Nidiformis.' Joe Stupka of Pulaski, Pennsylvania is credited with initially distributing propagation material across the central U.S.
