Scented Christmas candles can bring back nostalgic memories. Some of us remember freshly cut Christmas trees. In fact, freshly cut Christmas trees still exist. But they are not without dangers. Even cool lights such as LEDs can short out. I once had a lighted piece intended as a tree topper start producing smoke. Fortunately, I was in the room and pulled the plug before the tree ignited. Such dangers are always present with trees, and the longer time it has been since the tree was cut the greater the danger of fire. Trees dry out no matter how much water is added regularly.
The option is to use an artificial, flame retardant, Christmas tree. These are also a good choice for minimizing the impact on the environment. But, artificial Christmas trees lack that fir or spruce smell. Using a scented candle can add that special aroma. Just choose the right scent. The candle does not go on the Christmas tree, just subtly adds the scent to the room. In fact, you can add that special scent to many rooms.
Other aromatic candles can be used to set a relaxing atmosphere, such as lavender. Or perhaps peppermint is more mood setting for the occasion.
