Drosera ramellosa

Branched Sundew

A small tuberous sundew from southwestern Western Australia, 2 to 12 cm tall, with one to three erect stems bearing alternate trap leaves and white to pink flowers from July to September. It grows through the cool, wet Mediterranean winter and spends the hot, dry summer as a dormant underground tuber, so cultivation depends on copying that winter-growing, summer-dry cycle.

Where it grows wild

Winter-wet clay, sandy clay and sandy soils: moss beds on granite outcrops, margins of swamps and creeks, damp flats and occasionally saline clay flats and samphire flats, in open heath, sedgeland and woodland. Specimen labels repeatedly mention mossy soil on granite.

Lowland to low hills, roughly sea level to a few hundred metres; no specimen records carry an elevation.

Australia: Western Australia (southwest, from Kalbarri and Geraldton south to Cranbrook and east to Cape Arid)
