Abies homolepis

Abies homolepis, widely known as Nikko fir, is an evergreen conifer in the family Pinaceae, order Pinales. It is native to the mountains of central and southern Japan, particularly on the islands of Honshu and Shikoku, where it grows in subalpine and upper montane forests at elevations typically between 1,000 and 2,500 meters. The species is named for the Nikko region of Tochigi Prefecture, a famous mountainous area where it is conspicuous. In its native habitat, Nikko fir forms forests with other conifers such as Japanese larch (Larix kaempferi) and various broadleaved deciduous trees. Mature trees are stately and pyramidal, reaching 25 to 35 meters in height, with strongly whorled horizontal branches. Bark is gray-brown and fissured with age. Needles are pectinately arranged, dark green above, with two clearly defined white stomatal bands beneath. The underside coloring gives foliage an attractive silvery appearance when viewed from below or when branches move in the wind. Seed cones are cylindrical, erect, and measure 6 to 12 centimeters in length, maturing from green to purple-violet before disintegrating on the branch. Abies homolepis is valued as an ornamental tree in temperate gardens worldwide, where it is admired for its regular architectural form and attractive, two-toned needles. It is considered more tolerant of air pollution and urban conditions than some of its relatives, contributing to its use in parks and larger gardens across Europe and North America.
