Abies grandis (Grand Fir)
One of the tallest firs in the world, Abies grandis (Grand Fir) is a large evergreen conifer of narrow, conical habit becoming round-topped or straggly with age. Its spreading and drooping branches are densely clad with sharp-tipped needles, shiny dark green above with two silver bands beneath. The needles are arranged in 2 distinct, flattened rows. They exude an orange aroma when crushed. Usually very resinous, the seed cones, up to 4 in. long (10 cm), are light-green or purple-tinged when young maturing to reddish-brown. Held upright along the branches, they create a lovely contrast against the deep green foliage. A fast grower, its gray bark is thin when young, thickening and becoming brown with age. Grand Fir makes a useful specimen tree.
