Picea abies 'Vassar Broom' is a dwarf globose mounding selection that will become more spreading with age. Branches are layered, turning upward at the ends with prominent cinnamon-brown buds at the tips, particularly in the winter. Needles are species-typical and medium-green in color. After 10 years, a mature specimen will measure 24 to 30 inches (60 - 75 cm) tall and slightly wider, an annual growth rate of 2 to 3 inches (5 - 7.5 cm).
This cultivar originated as a witch's broom that originated in the U.S. at some point in the mid-1980s. No other origin data is available at this time.
