American bladderwort
Also known as: Bladderwort
American bladderwort (*Utricularia vulgaris*) is a free-floating carnivorous water plant that inhabits Europe and Western Asia. It does not anchor itself permanently in soil, and its branches die back in winter, leaving only a turion from which to grow the next spring. The eponymous bladders trap tiny invertebrates which can then be digested.

Water: American bladderwort thrives in aquatic environments, fully submerged with high water level tolerance. It requires consistent hydration, ideally watered twice a week, to support its carnivorous lifestyle. As an aquatic perennial, american bladderwort benefits from outdoor settings that replicate its natural dynamic water interactions.
Pruning: American bladderwort is an aquatic plant featuring bladder-like traps for prey capture. Prune in early to late spring by removing dead foliage to encourage new growth and prevent overcrowding. Clean tools before use to avoid contamination, ensuring a healthy aquatic environment.
Propagation: American bladderwort is a carnivorous aquatic plant known for its leaf traps for small creatures. Propagation occurs through division of rhizomes or shoots, ensuring each section has a growth point. Replant in wet, nutrient-poor medium to mimic habitat, allowing for adaptation into mature plants.
Repotting: Repot american bladderwort every 2-3 years in spring using a wide, shallow container. Provide full sun and maintain nutrient-poor, acidic water. A well-managed aquatic environment is essential for american bladderwort's health, making it relatively demanding in care.
