Utricularia gibba, the aquatic Humped Bladderwort, is available for sale online. It is a small size, mat producing perennial with bright yellow summer flowers. It grows floating in boggy waters with no roots. It is prolific and can form large, dense, floating mats. Its 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, growing under and among emergent aquatic plants, such as water lilies, frogbit and pickerel weed. Its flowers reach 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. The Humped Bladderwort is a wonderful plant for the garden bog pool or aquarium. Utricularia gibba is fast growing, but easier to control than duckweed. It can be an invasive weed in warm climates. Cultures may contain small amounts of other aquatic plants.
