Eupatorium resinosum, the pine barren thoroughwort, is a rare North American plant species in the family Asteraceae.

It formerly grew in New York and Delaware, but is now apparently extirpated there.

[3][4] Eupatorium resinosum has stems up to 100 cm (40 inches) tall and produce short rhizomes.

The inflorescences are composed of a large number of tiny white flower heads with 7-11 disc florets but no ray florets.

[6] It is rare, with only dozens of populations known, and has been extirpated from several states due to habitat destruction.
