Abies procera, or noble fir, is a non-native tree to Ontario but is native to the western US and is the largest of the true fir species, but are relatively rare in the nursery trade. This species will thrive on a variety of soil textures (coarse to fine) if there is adequate moisture. It is particularly suited for high elevations, cool, moist, and well-drained conditions. While mature trees are relatively free of serious pests and disease, it is highly susceptible to balsam woolly adelgid. Noble fir is moderately windfirm and is considered a shade-intolerant pioneer species. Noble firs tend to be difficult to transplant and may require additional irrigation maintenance to help it through its establishment phase.
