Description and habitat

Hymenocallis coronaria requires a swift, shallow, water current and direct sunlight to flourish.[5] The plant grows to about 3 feet (0.9 m) tall and develops from a bulb that lodges in cracks in rocky shoals.[6] It blooms from early May to late June.[5] Each fragrant flower blossom opens overnight and last for one day. They are visited and possibly pollinated by Paratrea plebeja, commonly known as the plebeian sphinx moth, and Battus philenor, the pipevine swallowtail butterfly.[7]

The plant was first observed in 1783 by

  • The Cahaba River Society
  • Cahaba River National Wildlife Refuge
  • Cahaba River Wildlife Management Area
