Drosera radicans

An erect tuberous sundew found only in a small area of the Geraldton Hills north of Geraldton, Western Australia. Its stems, 7–18 cm tall, carry small cup-shaped carnivorous leaves and white flowers in August and September. Like other tuberous sundews it grows through the cool, wet winter and spends the hot, dry summer as a dormant tuber underground.

Where it grows wild

It grows in winter-wet ground in sand or sandy clay in the Geraldton Hills, in low heath and open woodland where the soil is damp through winter and dries out completely in summer.

Lowland to low hills, roughly 50–250 m in the Chapman Valley and Northampton areas; no elevation data were measured.
