Utricularia intermedia, Flat-leaf Bladderwort, is a medium growing, perennial, aquatic bladderwort. It grows suspended in the boggy waters with no roots. Its leaves are finely divided. Bladders are found on whitish stolons growing through the substrate. 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 May to November. They are large and bright yellow. As Fall approaches, it forms turions (winter buds), which settle to the bottom, and help it survive winters. If it is grown in temperatures above 55°F (12°C), it will continue to grow through the winter. Grows best in and amoung emergent plants such as pickerelweed. It can become weedy and invasive in water bogs. This is a great plant for the garden bog pool or aquarium, and will help reduce the mosquito population.
