Abies concolor 'Rockford' / Rockford white fir

Abies concolor 'Rockford' is a miniature, low mounding bun selection with perfectly symmetrical, short, dense branching; and shorter-than-typical blue-green foliage. After 10 years of growth, a mature specimen will measure 12 to 18 inches (15 - 20 cm) tall and wide, an annual growth rate of around 1 inch (2.5 cm).

This cultivar originated as a witch's broom found in the early 1990s by Dennis Hermsen of Farley Iowa. Denny found the original broom on the grounds of Rockford Cemetery, Rockford, Illinois.
