Common names include spotted beebalm and horsemint.[1] It is a thyme-scented plant with heads of purple-spotted tubular yellow flowers above rosettes of large white- or pink-tipped bracts. The plant contains thymol, an antiseptic and fungicide.[2] It was historically used to treat upset stomachs, colds, diarrhea, neuralgia and kidney disease. Varieties
DescriptionUnlike the most familiar Monarda species that have a single flower head on a stem, Monarda punctata has flowers that are stacked up the stem with bracts radiating from the stem, under each flower. Varying in color from light pink to white, the bracts are ornamental longer than the flowers, whereas the flowers (yellow with brown spots) are visible only at close range.[4] Ecological ValueM. punctata attracts pollinators in great numbers, especially wasps. Among the wasps that it brings to the garden are beneficial predatory wasps that control grubs, pest caterpillars, and other harmful insects.[4]References1. ^1 {{GRIN|24538|Monarda punctata L.| accessdate = 2011-10-10}} 2. ^{{cite book |first=Matt |last=Turner |title=Remarkable Plants of Texas: Uncommon Accounts of Our Common Natives |publisher=University of Texas Press |location=Austin |year=2009 |isbn=0-292-71851-9 |pages=241–243}} 3. ^{{ITIS |id=32279 |taxon=Monarda punctata |accessdate=2011-10-10}} 4. ^1 {{Cite news|url=http://mtcubacenter.org/trials/monarda/monarda-punctata/|title=Monarda punctata - Mt.
