Note: recent evidence indicates that the apparent Abies concolor found in Oregon forests are actually a hybrid between Abies concolor and Abies grandis, Grand Fir, and are now designated as Abies concolor × grandis.

The grand fir is one of the tallest firs, reaching heights of 300 feet. It is easily distinguished from other Pacific Northwest firs by its sprays of lustrous needles in two distinct rows.
