Drosera rosulata

A tuberous rosette sundew from southwestern Western Australia. It forms a flat rosette about 7 cm across in the cool, wet winter and flowers white from April to June. Then it dies back to an underground tuber for the hot, dry summer. Success depends on copying that cycle: grow it cool, bright and wet in winter, and keep it dry and dormant in summer.

Where it grows wild

It grows in sandy and clayey soils at the margins of swamps and seasonally wet flats. These are low-lying winter-wet ground within jarrah forest, wheatbelt nature reserves and coastal-plain heath. The rosette lies flat on open ground among low vegetation.

It grows at lowland to low-upland elevations, from the Swan Coastal Plain up to the Darling Plateau and wheatbelt, roughly 0–400 m. GBIF records do not give elevations.
