Bladderwort is a fascinating free-floating aquatic carnivorous plant that captures tiny aquatic organisms using bladder-like traps, making it ideal for wildlife ponds and water features. It requires clean, nutrient-poor, slightly acidic water and full to partial sunlight to thrive — avoid adding fertilizers to the water. Best suited for outdoor ponds in temperate climates, where it overwinters as dormant buds that sink to the pond bottom.
