Abies concolor ‘Olson’

Abies concolor 'Olson' is a tight, compact selection of white fir with light-blue needles that are shorter than those typically seen in the species. After 10 years a mature specimen will measure 14 inches (35 cm) tall and somewhat wider, suggesting an annual rate of growth of barely 1 inch (2.5 cm).

This cultivar originated as a witch's broom found 2001 by Justin "Chub" Harper of Moline, Iowa at a private residence in Davenport, Iowa and named for the property owner where it was found. It is occasionally seen listed as Abies concolor 'Olson Broom.'
