Description
The most heat and humidity-tolerant Fir we’re aware of, Abies firma, commonly known as the Momi Fir or Japanese Fir, can be enjoyed by outdoor gardeners as far south as USDA Zone 9b in central Florida and elsewhere across the South and is also cold hardy to Zone 6a, where average winter low temperatures can be -10F. It has some of the most unique and attractive foliage of any fir tree, resembling the foliage of Cephalotaxus harringtonia (Japanese Yew). The deep green needles in rows along the twig appear like a comb but with two rows of needles on each side of the twig in a V-shaped pattern. Green upright conical seed cones appearing as candles up to 5 inches long emerge green in spring, maturing to yellowish-brown, and remain showy throughout summer. Once a planted specimen roots into the soil, it will add about 12 inches in height per year, forming an upright pyramid from 40 to 60 feet tall and 20 to 30 feet wide at maturity. The Japanese Momi Fir is excellent as a specimen or in spaced groupings or privacy screen plantings. It also makes the perfect Christmas tree for gardeners in the warmer USDA Zones of 6a-9b!
Landscape & Garden Uses
Growing 40 to 60 feet tall and 20 to 30 feet wide at maturity, the Japanese Momi Fir is ideal as a focal point specimen or in privacy screen plantings and sunny woodland borders. It is also excellent for framing entrances or the corners of buildings. If pruned annually, it makes for a dense, outdoor Christmas tree. It is a fine addition to conifer gardens, rock gardens, or formal gardens (if pruned to a formal shape).
Suggested Spacing:Â 10 to 15 feet apart for staggered-row privacy screens; 32 or more feet apart for space between trees
Growing Preferences
The Japanese Momi Fir is easy to grow in moist, well-drained soil of average fertility and full sun (6 or more hours of sunlight daily). It has good drought tolerance when established but will appreciate supplemental water during extended summer droughts during its younger years. Constantly soggy or wet soils can be problematic, leading to root rot or other harmful plant diseases. So make sure to plant it in well-drained soil. No pruning is required; however, it responds well to it to make a more formal appearance or for an outdoor Christmas tree.Â
