Asian bladderwort

Utricularia uliginosa is a small annual carnivorous plant that grows as a terrestrial or submerse plant in seasonally flooded shallow pools with sandy soils or on banks and among rocky stream beds at low altitudes. Flowering occurs seasonally during summer or the dry season, when the water level drops slightly to expose the plants to air.

Native to: Borneo, Caroline Is., China Southeast, Hainan, India, Japan, Jawa, Korea, Malaya, Marianas, Myanmar, New Caledonia, New Guinea, New South Wales, Nicobar Is., Northern Territory, Queensland, Sri Lanka, Sumatera, Taiwan, Thailand, Vietnam, Western Australia.

Plant care

Utricularia uliginosa has small blooms that are coloured bluish-purple. Oftentimes, only cleistogamous flowers are formed, which never open fully and are self-pollinating. The lower corolla lip has a helmet-like dome at the center which is lighter in colour, developing into shallow lobes at the edge. The upper corolla lip is small. the spur is broad at the base and steadily tapers to a point, forming an overall triangular shape. The leaves are commonly seen and grassy appearance. When they are fully submerged, the leaves can be quite long and thin, although when growing emersed they tend to be shorter and more oval in shape.

Water care

Originating from nutrient-poor waters Utricularia uliginosa survive by forming the bladder traps – a unique feature of this family, which Utricularia species form after a short period also in the aquarium.
