Abies concolor 'Masonic Broom' is a very scarce and extremely choice selection of white fir grows as a tight, compact, little flat-topped bush with knuckled branchlets of gray-blue needles that are a little smaller than those of the species. After 10 years, a mature specimen will be only 2.5 to 3.5 inches (7 - 8 cm) tall and 8 inches (20 cm) wide, making it an excellent choice for a xeric rock garden.
This cultivar originated in 1978 as a witch's broom found on a specimen of 'Compacta' at a Masonic Home in Pennsylvania by Joel W. Spingarn of Baldwin, Long Island, New York and introduced to the nursery trade by Ed Rezek and Hillside Gardens, Lehighton, Pennsylvania, USA.
