Definition

Noun A silver fir is any of various true fir tree species (genus Abies) whose needles have a distinctive white or silvery-white underside. This characteristic gives the foliage a two-toned or silvery appearance.

Usage and Examples

The term is used to identify and describe specific types of fir trees based on a key botanical feature. * The silver fir is prized in landscaping for its attractive, bi-colored foliage. * We collected cones from a mature silver fir in the forest. * The wood of the silver fir is often used for construction and paper pulp.

Advanced Usage and Notes

• The silvery effect is caused by stomatal bands (lines of pores) on the underside of the needles.
