Eupatorium paludicola, also called swamp justiceweed,[1] is a rare North American species of plant in the family Asteraceae, found only in the States of North Carolina and South Carolina in the southeastern United States.[2][3]
Eupatorium paludicola was for many years considered part of E. leucolepis until chromosomal analysis showed it to be a distinct species.[4][5]
Eupatorium paludicola is a perennial herb spreading by means of underground rhizomes. It has long, narrowly lance-shaped leaves. Hybrids have been reported between E. paludicola and E. mohrii.[6]
