About

Bartonia paniculata, commonly known as twining screwstem, is a saprophytic, annual or biennial species that grows in acidic, sandy-peaty wetlands.

Where it grows

Bartonia paniculata is the northernmost-ranging species in the genus Bartonia. It is found along the Atlantic coastal plain; its widespread range crosses 29 American states and five Canadian provinces, and overlaps with that of Bartonia virginica. The subspecies texana is found in eastern Texas and northeastern Louisiana; it was previously identified as Bartonia texana.
