Which species has the common name Grand Fir?

The species that is commonly known as Grand Fir is Abies grandis. This species is a member of the Pinaceae family and is native to the western United States, particularly in the Pacific Northwest region. Grand Fir is characterized by its tall, straight trunk and soft, fragrant needles that are typically arranged in a flat manner. It can grow to impressive heights and is often found in moist mountainous areas.

The common name "Grand Fir" is derived from its size and grandeur compared to other fir species. It also plays a significant role in forest ecology and is valued for its timber. In contrast, Chamaecyparis obtusa (Japanese falsecypress) and Calocedrus decurrens (incense-cedar) are not firs, but rather belong to different genera and families, while Cedrus atlantica (Atlanttic cedar) is a true cedar, also distinctly different from fir trees. Understanding the distinguishing features of these species helps in recognizing their placement within horticulture and forestry.
