Douglas fir (scientific name: Pseudotsugamenziesii) has a heartwood of light brown color with a hint of yellow or red (color varies with age and location of tree). Its texture is medium to coarse, its luster is moderate, and its grain is usually straight – sometimes slightly wavy.
When quarter cut/sawn the grain is straight and plain. Flat cut/sawn wild grain patterns are seen.
Douglas fir is commonly found in western North America. It is moderately durable but prone to insect attack.
