Drosera sulphurea

A scrambling tuberous sundew from the south coast of Western Australia, with small shield-shaped trapping leaves on stems 40–60 cm long and yellow flowers in spring. Like other tuberous sundews it grows through the cool, wet winter and dies back to an underground tuber for the hot, dry summer. It grows in sandy loam, often near Cephalotus, so a winter-growing, summer-dry cycle is essential in cultivation.

Where it grows wild

Coastal heath and scrub of south-west Western Australia, in sandy loam, often among Cephalotus follicularis, which points to damp, seasonally moist sites. The stems scramble through low shrubs for support.

Only 6 records carry an elevation: 10–90 m, median 25 m. It is a low-altitude coastal plant.
