Drosera banksii

Banks' sundew

A small annual sundew of the monsoon tropics of northern Australia and New Guinea, with a rosette of kidney-shaped leaves on stalks and 5 mm white flowers. It germinates when the wet season arrives, grows in wet sand around seeps, creeks and swamp margins, sets seed and dies as the ground dries. At home it is grown as a hot, bright, wet-season annual and kept going from seed.

Where it grows wild

Herbarium labels place it in damp to soggy sand and sandy loam: seepage areas in savanna woodland, Melaleuca swamps and ephemeral wetlands, creek banks and drainage lines, damp sand on sandstone pavements and plateaus, and billabong margins. The surrounding vegetation is open Eucalyptus or Melaleuca woodland with grasses and sedges, so the plants are largely in the open.
