Purple Bladderwort - Utricularia purpurea
Purple bladderwort is actually just one of three bladderworts with lavender flowers. Florida purple bladderwort (U. amethystina) is confined to a few counties in Collier and Lee Counties in extreme southwest Florida while lavender bladderwort (U. resupinata) , also found statewide, is distinguished by an upcurving lower lip. The plants photographed here were observed in shallow water at Kissimmee Prairie Preserve State Park.
Purple bladderwort spreads across the open water by forming a network of below-water stems. The light purple flowers can occur throughout the growing season. They stand several inches above the water and are about 1/2 inch in length. The lower lip is accented with a broad yellow and white splotch and a deeper purple splotch is evident on the upper petal.
Though bladderworts are interesting plants, they don't lend themselves to nursery propagation. None of the 14 native species are currently offered by nurseries affiliated with the Florida Association of Native Nurseries (FANN) and I am not aware of them ever offering any of these plants. Look for it in shallow water habitats, but you'll have to look closely as its small size sometimes makes difficult to see.
