Abies concolor 'Frosty' is a dwarf, upright, tree-form of white fir with a nice dense, pyramidal growth habit. New growth is lemon-yellow in full sun, while the undersides of the needles tend to develop a pale grey green look while top of needles (in sun) retains a pale yellow appearance throughout the year. Thus, on sunny days the reflection from bright light tends to mute the color but on overcast bright days, the tops of the needles glow brightly. Needles turn pale grey green if grown in partial shade.
After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) tall and 2 feet (60 cm) wide, an annual growth rate of 4 to 6 inches (10 - 15 cm).
This cultivar originated a color sport found in 2000 by Paul Surian and William C. Snyder of Kalamazoo, Michigan. Blue Horizon Nursery of Grand Junction, MI is credited with introducing it to the nursery trade.
