Abies alba 'Pyramidalis' is a narrowly conical, fastigiate selection of European silver fir with dense, erect branches, and short, glossy, dark-green needles with silvery undersides. It's overall structure is tightly pyramidal when young, but over time, an older plant will take on more of a narrow, conical shape. After 10 years in the landscape a mature specimen will measure 10 to 13 feet (3 - 4 m) tall and 3 to 5 feet (1 m) wide, a rate of growth of nearly 1 foot (30 cm) per year.
This is a very old cultivar, most likely originating in Germany in the early 1800s before making its way to the United Kingdom around 1950, then to the United States around 1970. It is virtually guaranteed to be found in any large, important conifer collection anywhere.
