Fragrant trees are a type of tree that produce a pleasant scent. The most common fragrant trees are fir, pine, and cedar. Fir trees are evergreen conifers that are native to the Northern Hemisphere. Pine trees are also evergreen conifers that are found in many parts of the world. Cedar trees are also evergreen conifers that are native to the Mediterranean region. All three of these fragrant trees produce a pleasant scent that can be used for aromatherapy or to create a calming atmosphere.
