Native to eastern North America. Bushy, leafy clumps grow 2 to 4 ft. high with an initial width of about 1 1/2 ft.; after that, they spread rapidly at edges but are not really invasive. Dark green, 4- to 6-in.-long leaves have a strong, pleasant odor like a blend of mint and basil. In summer, upright stems are topped by tight clusters of long-tubed flowers much visited by hummingbirds. Divide every 3 or 4 years. Not long lived in areas with warm winters and long, hot summers.
Basic species has scarlet flowers surrounded by reddish bracts. All bloom over long period of 2 months or more when spent flowers are removed. Don’t let soil dry out.
