↑Habitat

Found in a variety of sunny to lightly shaded wetlands, including bogs, marshes, and margins of ponds and streams. In the south of its range it is limited to sinkhole ponds in mountains and interdune depressions along the coast. It is less common in anthropogenic habitats but grows in commercial cranberry bogs and may be spread to new regions with cranberry plants.
