Pseudotsuga menziesii var. glauca, known as Rocky Mountain Douglas Fir, is a robust conifer ideally suited to northern and northwestern climates, growing best in medium to wet, well-drained soils with full sun exposure. This variety thrives in areas with abundant air and soil moisture, although it is not recommended for hot, humid regions with drought. Standing majestically at 50-80' in cultivation, it can reach over 300' in the wild, showcasing unique forked cone bracts that set it apart from other conifers. Its pendulous cones are up to 3" long, and its blue-green needles are fragrant when bruised, with distinctive white banding underneath. The tree's growth form transitions from narrow pyramidal to cylindrical as it matures, characterized by a dense top crown. Renowned for its impressive winter hardiness, particularly in USDA Zone 5, this variety is celebrated for its timber and ecological value. It's essential to monitor potential issues like fungal diseases and pests, including the Douglas-fir beetle, to maintain its health and grandeur. Whether for timber or forestry purposes, Rocky Mountain Douglas Fir is a splendid choice.
