Botanical Name:Pseudotsuga menziesii
Common Name:Douglasfir, Douglas-fir, Douglas fir
Family Name:Pinaceae – pine family
General Description:Pseudotsuga menziesii is highly valued as a timber tree, as a stately forest tree and as an ornamental tree for the landscape. It is native to North America throughout the Rocky Mountains and Pacific coast where it is typically the largest tree in the forest. Pseudotsuga menziesii is considered one of the largest trees in the world. Even under cultivation here in the Midwest it can reach well over 40 foot tall. The Rocky Mountain geographical variety Pseudotsuga menziesii var. glauca is considered the best choice for use in the Chicago area as it has better winter hardiness. Douglasfir is best used on large scale sites, in full sun and in moisture retentive soils. Wind and drought is problematic for this plant. There are several cultivars available from specialty nurseries, primarily selected for foliage and form qualities. The cultivars may be better suited for the residential landscape than the species.
