Ultimate Guide to Growing and Caring for Noble Fir Trees
Noble fir, scientifically known as Abies procera, earns its moniker “noble” for being the largest American fir species and the largest of all true firs. Originating from the mountains of the Pacific Northwest, where it can reach towering heights of 180 to 270 feet, this majestic evergreen is often grown as a specimen tree in large, open landscapes. Due to its popularity as a Christmas tree, the noble fir is commonly referred to by this festive nickname.
Characteristics of Noble Fir
- Bark: Silvery-gray
- Needles: Gray-green or bright blue-gray
- Branches: Stiff, short, almost horizontal growth
- Crown: Conical in youth, rounding out with age
This long-lived tree doesn’t begin producing seeds until it reaches around 50 years of age. Noble fir not only offers aesthetic appeal but also serves as a vital food source and shelter for various bird species like chickadees and jays, as well as other wildlife.

Common Pests and Diseases
Fir trees, including noble firs, are susceptible to various pests and diseases. Common issues include aphids, mites, and adelgids, as well as fungal diseases like root rot and needle blight.
