Utricularia chrysantha

Sun bladderwort

A medium-sized annual terrestrial bladderwort of the monsoon tropics of northern Australia and southern New Guinea, with tall stems of bright yellow flowers. It lives in seasonally waterlogged sedgeland and open Melaleuca woodland, grows and flowers in the hot wet season, and dies after seeding when the ground dries. At home, grow it each year from seed in full sun, keeping it hot and wet.

Where it grows wild

Seasonally wet grassland, sedgeland and open Melaleuca–Acacia savanna near sea level. Records from the Northern Territory describe open Melaleuca nervosa and M. viridiflora woodland over sedges and grasses, where the sandy or peaty ground is saturated or shallowly flooded during the wet season.

Low elevations, close to sea level.
