Humped Bladderwort Utricularia gibba

Description

Floating Bladderwort is a carnivorous plant found in NC and all other continents in the world besides Antarctica. It forms mats of crisscrossing, branching, thread-like stolons each growing to approximately 8-10 inches long. They can be free-floating or loosely rooted in the substrate of shallow water. The traps among the leaf-like structures are for capturing tiny water creatures.

The small two-lipped flowers are generally held above the water and can occur anytime during the growing season. Plants that are rooted in the substrate generally bloom more. It generally prefers shallow and slow-moving waters in full to partial sun. They can be grown in a container or bog garden. This plant can become weedy.

Habitat: Ponds, lakes, bogs, marshes and ditches
