The carnivorous Utricularia vulgaris plant, or Common Bladderwort, is a medium size, perennial, 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, growing under and among emergent aquatic plants, such as water lilies, frogbit and pickerel weed. Utricularia vulgaris flowers reach above the water in mid summer. As Fall approaches, it forms turions (winter buds), which settle to the bottom, and help it survive winters. Some refer to the N. American species as Utricularia macrorhiza. This is a wonderful plant for the garden bog pool, and will help reduce the mosquito population.
U. vulgaris 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.
