Drosera rotundifolia

Round-leaved sundew

The most widespread sundew in the world, a small rosette of round, sticky leaves on long stalks that grows in acid sphagnum bogs across Europe, northern Asia and North America. It survives winter as a tight resting bud (hibernaculum) and must have a cold dormancy each year to stay healthy. Given full sun, cold winters and pure water, it is an easy outdoor bog plant.

Where it grows wild

It grows in open, sunny or partly sunny acid wetlands: sphagnum bogs, poor fens, wet heath, boggy lake shores and wet black spruce stands. It often sits on or in living sphagnum hummocks, which keep it wet and acid and reduce competition.

Mostly lowland to montane. The measured sites are lowland (0–217 m) in the north-eastern USA, the Netherlands and southern England.
