Common bladderwort is a perennial aquatic bladderwort that grows suspended without roots. Bright yellow flowers bloom throughout the summer and are significantly larger than other similar species. It can grow aggressively and may need to be maintained often to control its spread.
Common bladderwort is a carnivorous plant that uses its bladders as elaborate traps. When a small organism brushes hairs near a bladder pore, the pore’s tiny door-like structure opens inward and water rushes inside, carrying the organism with it.
