Douglas‑fir (Pseudotsuga menziesii) and its hardy cousin, Pseudotsuga menziesii var. glauca, are two of the most underrated evergreen trees for Ontario landscapes. Known for their soft needles, elegant form, and impressive year‑round colour, these conifers thrive when planted in the right location. The Rocky Mountain variety, in particular, offers exceptional cold hardiness and adaptability, making it a strong alternative to common spruces and pines. In this post, we explore where Douglas‑fir performs best in Ontario, the pests and diseases to watch for, and a few fun pieces of trivia—including why this iconic tree isn’t actually a true fir.
