Our North American plants are sometimes treated as a full species (S. parviflorus) distinct from European valerandi. However, Jones et al. (Plant Syst. Evol. 298: 1523-1531, 2012) produced both nuclear and chloroplast sequence data, along with morphological studies, that show the North American material (although clustered together) embedded within S. valerandi. Therefore, distinguishing the continental phases as subspecies seems like the more appropriate approach.
Tidal freshwater and oligohaline marshes, tidal swamps, alluvial swamps, floodplain sloughs and pools, maritime swamps, interdune swales, calcareous seepage swamps, rocky and sandy riverside bars. Frequent in the Coastal Plain; infrequent in the Piedmont and mountains.
