Drosera heterophylla

Swamp rainbow

An erect tuberous sundew from south-western Western Australia, 10–30 cm tall. It is unusual in the genus for its many-petalled white flowers. It grows in winter-wet swamps, often in shallow water, and on wet clay flats near granite outcrops, flowering from June to September before dying back to its tuber for the hot, dry summer. Success depends on mimicking that cycle: a cool, sunny, wet winter and a dry summer dormancy.

Where it grows wild

Swamps, often in shallow water, wet clay flats and seepage areas around granite outcrops. These sites fill with water in the winter rains and dry out completely in summer.

It is a plant of the low coastal plain and inland plateau of south-western Australia, mostly below about 400 m.
