Description
An evergreen coniferous tree, Abies balsamea, native to the northeastern United States and Canada. The fragrant, light yellowish brown balsam fir timber has a coarse but even grain. The wood is brittle and not very durable. It is used for packing boxes and paper pulp. Balsam fir produce a viscous oleoresin called Canada balsam.
Synonyms and Related Terms
