Very popular in the US since the 1920s, the Douglas fir has soft, dark green or blue green needles. The tree is popular for its good needle retention and a lovely citrus fragrance.
Apart from the coast redwood, douglas fir is the tallest tree growing on the North American west coast. They are large and vigorous evergreen conifers. They are great for poor soil, as long as the site is not dry. Mature trees in the open have a lush, attractive canopy. It can be grown as a screening tree up to about 55+ metres high. It is a good tall windbreak tree.For such a big tree, the Douglas Fir has a fairly compact canopy, with downward pointing lower branches that do a great job of blocking out sight from about 5metres off the ground when they are mature. Older trees have a very thick, corky bark with lovely sinuous ridges.
