Drosera gigantea
One of the largest sundews: a tuberous, branching, shrub-like species 20–100 cm tall, from south-western Western Australia, with small shield-shaped trap leaves along its lateral branches. It grows through the cool, wet Mediterranean winter and dies back to a deep tuber in the hot, dry summer. It is one of the easier tuberous sundews, but it needs a deep pot, a cool growing season and a summer rest.
Where it grows wild
Damp to seasonally wet sandy soils at the margins of swamps, in winter-wet heath and near granite outcrops. The subspecies geniculata favours black peaty sand around Perth and to the south. It is anchored by a large tuber, up to about 3.8 cm across, that can sit up to a metre deep.
It grows on the coastal plain and nearby ranges. The 14 records with an elevation span 10–329 m, median 87 m.
