Utricularia australis

A free-floating, rootless aquatic bladderwort of still fresh water in Australia and New Zealand. Its trailing stems carry tiny traps that catch water fleas and other small animals, and in summer it puts up yellow flowers above the surface. It is easy in a sunny tub or pond of soft, nutrient-poor water. Cold-climate forms survive winter as dormant buds (turions).

Where it grows wild

Floats just below the surface in lakes, lagoons, swamps, farm dams, billabongs and slow streams, in soft, often slightly acidic, nutrient-poor water, usually among reeds, sedges and other water plants.

Mostly lowland. Recorded elevations run from 0 to 762 m, median 52 m (99 records).
