Wild Bergamot (Monarda fistulosa) Wild bergamot is one of several wild mints to be found in the tall-grass prairie. The twisted, bugle-like flowers form a dense head, rising to about 45 cm, opening in mid-July. The plants prefer drier, well drained sites and grow as small clumps, spreading by short rhizomes. All parts of the plant are mildly aromatic.
