Lamiaceae (Mint Family)
USDA Symbol: MOCI
Known by a number of common names, lemon beebalm is a 1-2 ft., aromatic winter annual with unusual, tuft-like, lavender to pink, whorled flower heads. Each whorl in the elongated spike is subtended by whitish or lavender, leaf-like bracts. Several stems grow from the base and are lined with pairs of lance-shaped leaves.
Horsemint has a distinctive citrus or lemony scent when the leaves are rubbed or crushed. It is very easy to grow and often forms large colonies. Bees and butterflies are attacted to this plant.
Linnaeus named the genus Monarda in honor of a 16th century Spanish physician and botanist, Nicolas Bautista Monardes (1493-1588). Monardes studied medicinal plants brought back to Spain from the New World.
