The green family has two categories: fresh and earthy. Anyone who’s ever had the pleasure of smelling a freshly cut Christmas tree has experienced a green scent firsthand. Balsam Fir essential oil has a similar fresh, evergreen scent that’s not only excellent for holiday blends but has many year-round uses. Fresh green scents might remind you of fresh grass, or a new garden in Spring. Earthy green scents evoke images of freshly tilled soil or leaves in the summer sun.
