Drosera derbyensis

A tropical 'petiolaris-complex' sundew endemic to the Kimberley of Western Australia, forming rosettes of woolly-haired petioles with small round traps and sending up stems of 30–50 white flowers from March to June. It grows in wet sand in floodways and beside rock outcrops under full monsoon sun, so it needs strong light, heat and constant moisture while growing.

Where it grows wild

Grows in sandy soils in seasonal floodways and near rock outcrops, in open savanna country that is flooded or waterlogged in the wet season and bakes dry for much of the rest of the year. The dense white hairs on the petioles are thought to help it resist drying out as the wet season ends.

Lowland: the Kimberley records lie mostly from near sea level to a few hundred metres. Few GBIF records carry an elevation, so this was not measured.
