Flatleaf bladderwort (Utricularia intermedia)

Flatleaf bladderwort

Also known as: Mountain bladderwort

The flatleaf bladderwort is a carnivorous plant that can survive in water either by rooting in the substrate or by floating. These plants trap and consume prey using sophisticated trapdoors in their "bladders." These bladders also host their own ecosystems of beneficial bacteria, algae, and diatoms.

Water: Flatleaf bladderwort thrives in wetland habitats with consistent moisture, requiring watering twice a week. This aquatic carnivorous plant captures prey in water-filled bladders and is influenced by seasonal water level fluctuations, which affect its growth and dormancy cycles.

Pruning: Flatleaf bladderwort is an aquatic carnivorous plant with buoyant floating stems. Prune during early to late spring to support healthy growth, thinning overcrowded areas to enhance light and water flow. Clean tools to prevent disease; effective pruning boosts nutrient absorption and overall vigor.

Propagation: Flatleaf bladderwort is a unique carnivorous plant that captures nutrients with bladder-like traps underwater. For successful propagation, sow seeds in wet, sunny conditions and keep the medium moist to replicate its natural habitat. Minimizing root disturbance is crucial to avoid transplant shock.

Repotting: Flatleaf bladderwort requires repotting every 2-3 years in spring using a shallow pot to accommodate floating growth. Provide full sun and avoid fertilizers, relying on its carnivorous diet. Use pure, mineral-free water to prevent root burn and ensure healthy development.
