Pseudotsuga menziesii, also known as Douglas Fir, Western Fir, or Oregon Pine, is an evergreen conifer that is a member of the pine or Pinaceae botanical family.  Named as the state tree of Oregon, it is native to western North America and is considered to be an invasive plant in New Zealand.  The trees were originally a member of the Abies genus but were eventually separated out into their own genus due to their very distinctive cone shape and are not considered to be a true fir.  Douglas Fir is a valuable timber tree in North America as well as a popular choice by many to use as Christmas trees.
 
Douglas Fir essential oil has a fresh, uplifting aroma that has a rich piney scent with a hint of lemon, that blends well with citrus, spice, and other fir oils.  It is popular, used both alone and added to oils such as Orange, Cinnamon, and Clove, for scenting the room during the Holiday season.  Try diffusing with Lemon, Lime, Black Spruce, and Tea Tree for a clean, invigorating aroma to freshen the air.
