Distribution


Sabatia kennedyana grows in wetlands, particularly lakes and ponds on the Atlantic coastal plain.[7] It grows in areas with fluctuating water levels and other forms of natural disturbance, such as ice scour, which eliminate competing vegetation.[8][9] It is a poor competitor with other plants.[10][5]


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.[6] It may be 5 centimeters wide, with 9 to 11 petals.[5]


Taxonomy


Sabatia kennedyana is considered by some authors as conspecific with Sabatia dodecandra.[11]


Conservation


Sabatia kennedyana is threatened by shoreline development, recreational activity, off-road vehicles, construction of hydroelectric dams,[6] pollution, and poaching.[5]
