A living plant not only spruces up any indoor space, but is a great gift for many other reasons. First, plants are great air purifiers, and second, they have proven mood-boosting benefits. Additionally, the plant you give your long-distance amour can become symbolic of your relationship. Just as a plant needs to be nurtured, watered, fed, and cared for in order to thrive, so too does your relationship. Plus, since plants live a long time when properly taken care of, when the two of you are finally together forever, the plant will be in your home reminding you both of the strength of your relationship.
