True to its name, the subalpine fir naturally occurs just below the timberline in mountain forests of the west and southwest of North America. It is often described as having a "spire-like" crown which is tall and very slender. Rarely used as an ornamental, it can make a good Christmas tree.
Care should be fairly straight-forward provided it is planted on an appropriate site. The subalpine fir performs best in the North or at higher elevations, so when you are planting it in a more southerly location, a north-facing slope is preferable.
In warm, humid climates, can suffer from root rot. Susceptible to sun scald in warm climates and is not tolerant of drought or pollution.
