Abies concolor 'Conica' / conical white fir

Abies concolor 'Conica' is a slow-growing, narrowly conical selection of white fir with dense, strongly fastigiate branches. Foliage is gray-blue in color and and needles measure only 1 inch (2.5 cm) long, shorter than is typical seem in this species. Annual rate of growth is 4 to 6 inches (10 - 15 cm) per year, resulting in a mature plant that is 4 to 5 feet (1.3 - 1.6 m) tall and 12 inches (30 cm) wide after 10 years in the landscape.

This cultivar originated as a unique form found in 1923 by B.H. Slavin in the Durand Eastman Park, Rochester, New York. In 1938, the plant was 11 feet (3.3 m) tall and 8 feet (2.2 m) wide. It was very rarely grown until the late 1980s when it became more prevalent in the nursery trade.
