Utricularia uliginosa, commonly known as Asian bladderwort, is a small annual carnivorous plant native to wetland habitats such as bogs, marshes, and the margins of slow-moving water bodies in Southeast Asia, Oceania, and Australia. It thrives in nutrient-poor, acidic soils where it supplements its nutrition by capturing small aquatic invertebrates in its bladder-like traps. This species often forms dense mats of foliage floating on the water’s surface or submerged, with slender, branching stems. The Asian bladderwort blooms from late spring to summer, producing small, bright yellow flowers that are quite showy despite their size.

The Asian bladderwort is valued for its unique carnivorous nature and can be a fascinating addition to water gardens and bog plantings. It requires consistently moist or aquatic conditions and full sun to part shade to thrive. While it is not typically grown for ornamental purposes, it can be an interesting specimen for those interested in carnivorous plants. Gardeners should be cautious, as Utricularia uliginosa can become invasive outside its native range, potentially disrupting local ecosystems. It is recommended to grow it in contained water features to prevent unwanted spread.CC BY-SA 4.0
