Perennial of the Lamiaceae family, native to the east and center of North America, where it colonizes dry to semi-dry prairies, forest edges, and sunny slopes. It is significantly more drought-tolerant than Monarda didyma, making it an easier species to cultivate in continental or Mediterranean climates.
It forms large bushy and branched clumps, reaching 80 to 120 cm in height. The stems are square, the leaves are ovate-lanceolate, slightly toothed, medium green, strongly aromatic. When crushed, they release a powerful scent reminiscent of oregano and thyme, due to the presence of thymol — which gave the plant a traditional medicinal use among several Native American peoples.
The flowers, tubular and slender, are gathered in dense terminal whorls, from pinkish lilac to lavender, borne on bracts tinged with pink or pale purple. In its natural habitat, flowering extends from July to September. In cultivation, it generally occurs from July to August.
It thrives in full sun in well-drained soil, even poor and dry. Its resistance to powdery mildew is noticeably better than that of M. didyma cultivars, which is a notable advantage. A division every three to four years is sufficient to maintain the vigor of the clump.
