- Description
-
Moni Fir is a needled evergreen conifer in the pine (Pinaceae) family that is native to hills and mountain slopes in central to southern Japan. The genus name is Latin for tree and the specific epithet is a reference to firm needles.
Moni fir will grow 40-70 feet tall in cultivation, up to 150 feet tall in its native habitat and 30-40 feet wide. It has a conical-pyramidal form. Plant in full sun or with some afternoon shade in average, consistently moist and slightly acidic soil. It is tolerant of clay soils. This fir is more tolerant of hot humid climates than most firs are and can be grown in the southeast.
The needles on this fir are strongly two-ranked on one side of the branch similar to a comb. Young needles have 2 sharp spines at the tips. The seed cones are held upright as is common for firs.
Use a specimen for a large yard, screening or as a Christmas tree.
Insects, Diseases, and Other Plant Problems: None serious. Possible insects are bark beetles, spruce budworms, aphids, bagworms, spider mites and scale. Potential disease problems include cankers, heart rot, root rot, needle rust, and twig blight.
