Drosera subhirtella

Sunny rainbow

A tuberous, scrambling sundew from south-west Western Australia that grows up to 40 cm with sticky leaves along its stems and bright yellow flowers from August to October. It grows through the cool, wet winter and dies back to an underground tuber for the hot, dry summer, so a dry summer dormancy is essential in cultivation.

Where it grows wild

Sandplains, granite outcrops and swamp margins in sand, clay and loam, often among eucalypt woodland on laterite, where it scrambles up through low vegetation.

Lowland and plateau sites of the south-west, roughly 0–450 m. Records rarely carry an elevation, so this is not measured.
