Bartlettina is a genus of flowering plants in the aster family, Asteraceae.[2][3][1] They are native to tropical regions of Mesoamerica and South America.[4] The genus was erected to house several plants separated from genus Eupatorium.[4]
These are shrubs or perennial herbs with woody bases. The oppositely arranged leaves have smooth or serrated edges. The flower heads contain tubular florets.[4]
The best known species may be the blue mist flower (B. sordida), which is cultivated as an ornamental plant[5] and has become naturalized outside its native range.[6]
