Douglasfir is a large and stately narrow conical conifer that is native to the Pacific Northwest (P. menziesii var. menziesii) and Rocky Mountains (P. menziesii var. glauca). Trees in native habitats are often taller than 100 feet; however, landscape trees rarely exceed 50 feet. Outside of its native range, douglasfir tends to be a relatively short-lived tree due to less than ideal growing conditions and to pest problems. Trees grown from seed from the Rocky Mountains tend to be more drought tolerant than trees grown from seed from the Pacific Northwest. Due to the potential pest problems, pines and spruces are more suitable choices when a conifer is desired in the landscape.
