Utricularia gibba, the Humped Bladderwort, is a small size, mat producing, perennial, aquatic bladderwort with bright yellow summer flowers. It grows floating in boggy waters with no roots. It is prolific and can form large, dense, floating mats. It's leaves are finely divided, and interspersed with small, scattered bladders, which turn dark from devouring infusoria. 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 reaching above the water from early Spring to mid Summer. Flowering seems to require growth in the peaty substrates of shallow warm waters. In Winter, it diminishes in size and drifts to the bottom of the pond, but does not seem to form turions. This is a wonderful plant for the garden bog pool or aquarium.
