Eupatorium anomalum, commonly called Florida thoroughwort,[3] is a North American species in the sunflower family. It grows in the southeastern United States from Alabama to Virginia.[4] Molecular investigations suggest that it originated as a hybrid between E. serotinum and E. mohrii but it is well-established on its own as a distinct species.[3]
Eupatorium anomalum is a tall perennial sometimes over 150 cm (5 feet) tall, producing tuberous rhizomes. It has opposite, egg -shaped leaves, and flat-topped arrays of a large number of tiny flower heads. Each head has 5 white disc florets but no ray florets.[3][5]
