Landscape Attributes

Compact Blue Rocky Mountain Fir is a dense multi-stemmed evergreen shrub with a distinctive and refined pyramidal form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance shrub, and usually looks its best without pruning, although it will tolerate pruning. It has no significant negative characteristics.

Compact Blue Rocky Mountain Fir is recommended for the following landscape applications;

  • Accent
  • General Garden Use

Planting & Growing

Compact Blue Rocky Mountain Fir will grow to be about 8 feet tall at maturity, with a spread of 5 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 70 years or more.

This shrub does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil pH, but grows best in sandy soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided. This is a selection of a native North American species.
