Eupatorium resinosum, or Pine barren thoroughwort, is a herbaceous perennial plant in Asteraceae native to the eastern coastal states of the United States, from North Carolina to New Jersey and Delaware.[2] The stems grow from 40 to over 100 cm tall and are produced from short rhizomes. The inflorescences are composed of a large number of white flower heads with disc florets and no ray florets.[3] This species typically grows in moist areas, areas with acidic soils, and pine barrens.[4] It is pollinated by insects and is self-incompatible.[5] It is rare, with only dozens of populations known, and has been extirpated from several states due to habitat destruction.[5]
