Pseudotsuga menziesii
Douglas Fir
Description
This majestic conifer is the state tree of Oregon as well as an Oregon native. It slowly reaches 50-100' tall and 20-30' wide. This evergreen tree has conical shape with densely packed needles, changing to a broad flat top with maturity. Bright green to deep green foliage cluster on lower drooping branches with upper branches ascending. This tree prefers sun to part shade with neutral or slightly acidic soil that is moist and well-draining. Young trees should be watered deeply but infrequently to establish a deep root system. Mature trees tolerate deep shade. To retain central leader branch, remove crossing branches. The bark of young trees is grey-green with highly scented blisters, and becomes purple-brown, thick and corky with horizontal fissures over time. Very long-lived tree; provides homes for wildlife.
