Monarda is a genus of 16 species of plants belonging to the mint family.
Plants are erect, herbaceous annual or perennial 20-90 cm tall. Leaves are opposite on the stem, thin, lanceolate with slightly serrated edges; range from smooth to slightly hairy, are 7 to 14 cm.
In all species of this genus, when you squeeze the leaves give a strong smell menthol. The species M. didyma contains the highest concentration of aromatic oils responsible for that odor. 
For cultivation prefer full sun and good drainage. American Indians used them for medicinal purposes.
Some species of Monarda plants are considered good companions for tomatoes, improving their health. They are generally good companion crop plants because they attract pollinators and some predatory insects and parasites or parasitoids that contribute to biological pest control.
