SYN: Nordmann Fir. Is an easy to grow, disease-resistant tree with dark green foliage. It’s one of the best trees to use as a Christmas tree because it retains its needles well, even when cut. Forms a shapely tree, not too bushy, with good space between the branches. Grow in a rich, free-draining soil in full sun for best results. Native to the Caucasus Mountains in Europe/Asia.
