Picea abies 'Wilson' / Wilson Norway spruce

Picea abies 'Wilson' is a very-slow growing, low mounding selection of Norway Spruce with dense symmetrical branching and short, light green needles. After 10 years of growth, a mature specimen will measure 6 inches (15 cm) tall and wide, an annual growth rate of less than 1 inch (1 cm). Plants are said to looks like a super-miniature form of P. abies 'Little Gem.'

This cultivar appears to originated in the U.S. in the 1980s. Beyond that, very little is known of it. In fact, Welch and Haddow in The World Checklist of Conifers, question its validity. An anonymous source says that the plant was found by Joe Stupka of Pulaski, Pennsylvania at the Mentor Heights Nursery, Mentor, Ohio. He named it in honor of the late nursery owner Horace Wilson. With that, it's possible that this plant is synonymous with P. abies 'Horace Wilson.'
