Flaigg, Norman G.
Monarda punctata L.
Spotted beebalm, Spotted horsemint, Horsemint
USDA Symbol: mopu
USDA Native Status: L48 (N), CAN (N)
An aromatic, erect perennial ranging from only 6 in. to almost 3 ft. tall. Rosettes of yellowish, purple-spotted, tubular flowers occur in whorls, forming a dense, elongated spike at the end of the stem or from leaf axils. Each whorl is subtended by large, conspicuous, whitish, purple-tinged, leaf-like bracts.
Linnaeus named the genus Monarda in honor of a 16th century Spanish physician and botanist, Nicolas Bautista Monardes (1493-1588). Monardes never went to the Americas but was able to study medicinal plants in Spain because Spain controlled navigation and commerce from the New World.

The tubular flowers are pale yellow spotted with purple on top of bracts that are white to light purple. Leaves smell like fine Greek oregano. This plant is propagated by seed sown in situ or in pots and transplanted to sandy, well drained soil. It can also be propagated by cuttings of young foliage. Drought tolerant but summer watering can keep plants fresh and blooming longer. Spotted beebalm can become aggressive. It is noticeably fragrant.
