Eupatorium mohrii, commonly called Mohr's thoroughwort, is a herbaceous perennial plant in the family Asteraceae native to the southeastern and south-central states of the United States, in the coastal plain from Virginia to Texas.[3] It has also been found in the Dominican Republic.[4]
Eupatorium mohrii is a perennial herb up to 100 cm (40 inches) tall and are producing tuberous rhizomes. As with other species of Eupatorium, the inflorescences contain a large number of tiny white flower heads, each with 5 disc florets but no ray florets. It forms hybrids with Eupatorium serotinum and Eupatorium rotundifolium.[3]
Distribution and habitat
Eupatorium mohrii is distributed from southeast Virginia south to South Florida and west to Texas.[5] It grows in moist areas, edges of ponds, and sandy soils,[3] as well as in moist pine savannas and other wet habitats.[5]
This species is commonly found in fire-dependent pinelands.[6] Its seeds can persist in the soil seed bank after a fire disturbance.[7]
