Drosera bulbosa

Red-leaved sundew

A tuberous sundew endemic to southwestern Western Australia. It forms a flat rosette of red-tinged leaves in the cool wet winter, flowers white from April to June, and spends the hot dry summer dormant as an underground tuber. There are two subspecies, bulbosa and major.
