Noteworthy Characteristics:
Horsebalm is a Missouri native plant that occurs in rich woodlands, ravines and wooded slopes, often in limestone soils, and typically grows 2-3 (less frequently to 4) tall. Features elongated, branching, loose, pyramidal, terminal clusters of tiny, 2-lipped, tubular yellow flowers in mid to late summer and large, sharply toothed, ovate, green leaves (4-8") on square stems. Foliage (when crushed) and flowers of this mint family member have a citronella-like fragrance. Leaves can be used to make teas, and the underground roots (rhizomes) were formerly used medicinally in the treatment of urinary and kidney problems and as astringents.
