White Fir (Abies concolor)

"Soft blue-green needles and a graceful, symmetrical form make the White Fir a symbol of quiet strength and year-round beauty."

Take a Moment: Stand beneath the branches and notice the soft texture of the needles and the gentle fragrance they release. Look upward to find the upright cones perched high in the canopy, a signature found only on true firs. White Fir reminds us that even the quietest trees can leave the most lasting impression.

Meet the Tree

White Fir is one of North America's most elegant evergreen trees. Its broad, symmetrical form and distinctive silvery blue-green needles create a calming presence in every season. Unlike many firs and spruces, its needles are unusually soft to the touch and release a refreshing citrus fragrance when gently crushed.

Native to the mountains of the western United States, White Fir thrives in a variety of climates and has become a favorite landscape tree for parks, campuses, and arboretums. Upright cones develop high in the canopy each year, gradually breaking apart to release their seeds while remaining perched on the branches, a hallmark of true firs.

Whether standing alone as a specimen tree or forming part of an evergreen landscape, White Fir offers beauty, structure, and year-round interest while providing shelter for birds and wildlife.

Wildlife Interactions

White Fir provides year-round shelter for songbirds, owls, and small mammals. Chickadees, nuthatches, crossbills, and squirrels feed on the seeds released from mature cones, while the dense evergreen canopy offers nesting sites and protection from harsh weather. Its branches create valuable winter habitat when deciduous trees are bare.

Did You Know?


Unlike spruce cones, which fall to the ground intact, White Fir cones remain upright on the branches and slowly disintegrate, releasing their seeds while leaving only the central spike behind. This is one of the easiest ways to identify a true fir.
