Abies nordmanniana 'Broom H' / Broom H Nordmann fir

Abies nordmanniana 'Broom H' is a dwarf, flattened globose selection of Nordmann fir with exceptionally dense branching and needles. Foliage is dark green in color with silvery undersides. With age, mature plants will develop a lead shoot and will become squatly conical, but will continue to be very tight and dense. After 10 years of growth, a mature specimen will measure 10 inches (25 cm) tall and 18 inches (45 cm) wide, an annual growth rate of 1 to 2 inches (2.5 - 5 cm).

This cultivar originated as a witch's broom found in the late 1990s by Greg Williams or Wolcott, Vermont, USA. Greg found the broom on the grounds of the H.H. Hunnewell Estate in Wellesley, Massachusetts. For many years there has been a great deal of controversy regarding the species name. Greg Williams didn't want to generate excess notoriety for the Hunnewell Estate, so it created the code name, 'Broom H.'

This well-known and highly desired conifer is also known by the following names.

  • 'Hunnewell Broom'
  • 'KBNG' or 'KBNG WB'
