Alligatorflag (Thalia geniculata) 
Alligatorflag (also known as fireflag) is a tall, sturdy herbaceous perennial. Compared to the overall size of the plant, its blooms are somewhat inconspicuous. Flowers are purplish to whitish, 3-petaled and often nodding. Leaves are large (3+ long), broadly lanceolate with long petioles and pointed tips. They emerge from the base of the plant. Flower stalks extend well beyond leaves.

Alligatorflag typically blooms summer through fall. It occurs naturally in wetland depressions and cypress sloughs, and along the edges of marshes, swamps and wet ditches.

Alligatorflag is the host plant for the Brazilian skipper (Calpodes ethlius). It also provides cover for nesting water birds.
