Drosera macrophylla

Showy sundew

The showy sundew is a tuberous Drosera endemic to south-western Western Australia. It forms a flat rosette of broad leaves up to about 4 cm long in winter and bears white flowers from June to October. It grows through the cool, wet winter and survives the hot, dry summer as a dormant underground tuber, and copying that cycle is the key to growing it.

Where it grows wild

Clayey, sandy or loamy soils, including around granite outcrops, in the Avon Wheatbelt, Geraldton Sandplains and northern Jarrah Forest. These are open woodland and heath sites where the low rosettes get strong winter sun.

Lowland to low inland plateau, mostly at a few hundred metres; the sources consulted give no altitudes.
