Taxonomic Notes


Proserpinaca pectinata is a dioecious perennial that grows as a forb/herb.[2] Flowers are red, orange, and green in color.[3]


This species occurs from Nova Scotia, south to southern Florida, and westward to western Louisiana. While it is primarily found along the coastal plain, it occurs inland, as far as Tennessee.[1]



P. pectinata occurs in bogs, savannas, ditches, and other wet places.[1] Along New York pond shorelines, this species is found on areas of organic exposed pond bottoms and permanently flooded zones.[4] In New Jersey pinelands, Proserpinaca pectinata occurred in 20% of ponds.[5]


In the southeastern and mid-Atlantic United States, flowering has been observed from June through October.[1][6]
