Distribution

Sabatia kennedyana grows in wetlands, particularly lakes and ponds on the Atlantic coastal plain.[5] It grows in areas with fluctuating water levels and other forms of natural disturbance, such as ice scour, which eliminate competing vegetation.[6][7] It is a poor competitor with other plants.[8][3]

Description

Sabatia kennedyana is a perennial herb with stolons tipped with basal rosettes of leaves. The flower is pink with a white or yellow center.[4] It may be 5 centimeters wide, with 9 to 11 petals.[3]

Taxonomy

Sabatia kennedyana is considered by some authors as conspecific with Sabatia dodecandra.[9]

Conservation

Sabatia kennedyana is threatened by shoreline development, recreational activity, off-road vehicles, construction of hydroelectric dams,[4] pollution, and poaching.[3]

gollark: Well, that's weird. It plays fine in `ffplay`, but not the browser.
gollark: I fully support this.
gollark: It would be convenient if my watch used one of those, so I wouldn't have to deal with the hassle of apparently needing to replace the battery every seven years.
gollark: Radioisotope generators are much cooler than wimpy "high-capacity batteries".
