Grand fir is a North American fir in the pine or Pinaceae family native to the Pacific Northwest through to Northern California, with coast and interior varieties. It can grow to a height of 80 m tall, the tallest fir species.

  • Needles are straight, quite variable lengths, 3–6 cm long and 2 mm wide, appearing to all lie flat in the same plane; colour is glossy dark green above and lighter underside, created by the lighter stomata bands; needles are slightly notched at the tip.
  • Needles are attached to the twig by a base resembling a small suction cup.
  • The species is monoecious; pollen cones are bluish-red, purple or orange; seed cones are 6–12 cm long, 3.5–4.5 cm wide, erect like other firs; they are fragmenting, disintegrating at maturity about 6 months after pollination.
  • Twigs are slender, buds ovoid; bark is gray, becoming moderately furrowed with age.
