It is also referred to as purple horsemint or lemon bee balm, and, not surprisingly, it belongs to the mint family. Its fragrant flowers are purple, and tend to bloom during the spring and summer. Parts of this plant can be placed into herbal teas and added to salads. The leaves are known for having a sweet smell that is reminiscent of citrus. - This plant tends to grow anywhere from one foot to three feet tall, and should be spaced out about two feet from each other when planted next to other lemon mint plants. It requires either partial or full sunlight, and though it may tolerate dry conditions temporarily, it does best in soil that constantly stays moist. The soil should also be either neutral, or only slightly acidic or alkaline. Lemon mint tends to do best in states that get plenty of sun and that have a lot of clay in the soil. It may be seen most often growing in prairies and along the side of the road.
