Horse Balm is also known as Rich Weed and Citroenella Horse Balm.

Plant is an upright, smooth to slightly hairy perennial with tuberous roots from which new growth emerges. Its preferred habitat is dense woods and wooded bluffs. Distribution is throughout the Escambia region.

Leaves are opposite on the stem; egg-shaped to widest in the middle; tapers to the tip with unequal sides or may be pinched at the tip. Leaf margins are toothed and the base is rounded or occasionally wedge-shaped.

The flowers are clusters at the end of a stem; bisexual in nature and symmetrical in form. The calyx is two-lipped and lobed. The corolla is yellow or white with two stamens that extend beyond the corolla. Flowers occur in mid-to-late summer.

Fruit is an ovary with two or more seed chambers.

The flowers have a lemon odor. The rootstock has been used medicinally as a diuretic, tonic and astringent, as well as a remedy for kidney and urinary problems.
