In 2016, the White House chose a Douglas fir to festoon the Obamas' final Christmas in the Executive Mansion, and for good reason: Douglas firs are gorgeous, equipped with soft needles that radiate out from the branches in all directions, and emit a sweeter scent if you crush them. The Douglas fir is native to western North America, occurring from British Columbia to Washington, Oregon, and California, parts of the Rockies and as far south as Yosemite. It's been one of the most common Christmas trees of the Pacific Northwest since the '20s and also exports to Hawaii, Guam, and other territories. Despite its name, it isn't a member of the genus Abies, and isn't a true fir at all. It's still a beautiful tree, and a favorite across the country.
