is a coniferous tree in the pine family Pinaceae. This tree is native to the mountains of western North America from the southern Cascade range in Oregon, south throughout California and into the Sierra de San Pedro Mártir in northern Baja California; east through parts of southern Idaho, to Wyoming; and south throughout the Colorado Plateau and southern Rocky Mountains in Utah and Colorado, and into the isolated mountain ranges of southern Arizona, New Mexico and northern Mexico. White fir live over 300 years and naturally occur at an elevation between 900–3,400 m (2,950–11,200 ft).
It is popular as an ornamental landscaping tree and as a Christmas tree.
The specific epithet concolor means "all one color".
Thanks to their regular-conical crown and straight, like a candle, the trunk, firs belong to the most interesting conifers. Fir needles are very decorative - in most species they are flat, glossy, dark green on the upper side and with white longitudinal stripes on the bottom. In several species, especially those growing in the mountains, needles are silvery-gray or gray-blue. In our gardens and parks, fir grows well on uniformly moist, fertile soils. Their beauty can only be observed in a completely free single planting. Care: does not like transplants. For 2-3 years after planting, it is recommended to add a wagon (150 g / m2). Loosening of the soil is carried out to a depth of 25-30 cm. You can mulch the near-trunk circle with sawdust, peat or chips with a layer of 5-8 cm. Young plants need shelter with spruce branches in severe winters.
Pruning: Sanitary pruning is done in early spring. Forming pruning is carried out in early spring before sap flow.Diseases and pests: affected by spruce-fir hermes. The seeds are damaged by the fir-cone rider. In winter, the needles can be damaged due to sudden temperature changes.
