Grand Fir (Abies grandis) - Description
A.grandis, like the name "grandis" implies, are commonly known as lowland/grand firs. It is one of the largest firs, reaching 300 feet in the wild (80-200 feet tall, 15-25 feet wide in cultivation). They bear dark green 1-1 1/2 inch long needles, with white lines beneath, growing in two rows along branches.

Fir trees are planted for screens and windbreaks. White fir is often planted as an ornamental in large parks.
