Grand fir is a very large evergreen conifer with flat, glossy needles arranged in two ranks and a narrow, spire-like crown. It grows in coniferous forests, tolerating shade when young and eventually towering over most companion trees.

Growing Giant fir

Grow Giant fir in part shade and medium water. Mature plants reach 1200 to 3000 inches tall and spread 300 to 420 inches wide.

Wildlife value

As a wind-pollinated conifer it offers little to pollinators, but its dense foliage and structure provide nesting and roosting habitat for birds.
