Your love of beauty comes in many forms. Share your appreciation with someone special by giving them a flowering plant. There's a variety of houseplants that help filter toxins like benzene, formaldehyde and trichloroethylene out of the air as well as adding color to a room. The peace lily or mauna loa (spathiphyllum) is both fragrant and oxygen-producing. It's easy to maintain and shows that you hope the air your honey breathes is healthy, just like your relationship.
