Utricularia floridana, Florida Bladderwort, is a large, perennial, tropical aquatic bladderwort with bright yellow summer flowers. It grows suspended in the boggy waters with no roots. Its leaves are finely divided, and interspersed with numerous bladders about 1/8", which turn dark from devouring infusoria, including mosquitoes. It prefers dark, tea colored, boggy waters rich in tannins. It does best in full sun, but growing among emergent aquatic plants, such as water lilies, frogbit and pickerel weed. Its flowers reach above the water in mid summer. If temperatures fall below 45 °F (7°C), it forms turions (winter buds), which settle to the bottom, and help it survive cooler temperatures. This is a wonderful plant for indoor growing.
