Facts

One variety of wild bee-balm (Monarda fistulosa var. rubra) has reddish purple flowers and is an escaped cultivar. The other two varieties are native to New England. This is a striking plant for the native garden, and good for attracting butterflies. Bee-balm is also used as a flavoring agent and in traditional medicine.

Variety rubra is non-native and known from CT, MA, ME, NH. Fernald (1901) over-reported this taxon because he considered Monarda media to be synonymous with this name. Variety fistulosa is native and known from CT, MA, ME, NH, VT. Variety mollis is native and known from CT, MA, ME, NH, RI, VT.

Native to North America?

Yes and no (some introduced)

Sometimes confused with
