Comments: Grand Fir is a large native tree that grows in the lower elevations throughout most of western Oregon and Washington, but also grows at elevations up to 5000 feet. It is usually easy to identify by its long needles that lie flattened on each side of the twig. It is shade tolerant, often growing slowly for years beneath large Douglas-firs. But if given a chance when some event creates an opening in the canopy, it can grow quickly to a large size often reaching to a height over 200’. Grand Fir is used to make lumber, plywood, and high-quality paper. Christmas tree lots often feature Grand Fir. Its dark-green needles and its strong fir-like fragrance make it a popular choice. Its stately appearance also makes it a popular choice for landscaping.
Best grown in rich, consistently moist, slightly acidic, well-drained soils in full sun to part shade. Best growth typically occurs in deep, rich, alluvial soils in moist, cool locations such as the Pacific Northwest.
