''Drosera rotundifolia'' — the round-leaved sundew or common sundew — is a species of sundew, a carnivorous plant often found in bogs, marshes and fens. One of the most widespread sundew species, it is generally circumboreal, being found in all of northern Europe, much of Siberia, large parts of northern North America, Korea, Japan and is also found on New Guinea.
== Morphology ==
The leaves of the common sundew are arranged in a basal rosette. The narrow, hairy, long petioles support long laminae. The upper surface of the lamina is densely covered with red glandular hairs that secrete a sticky mucilage.
A typical plant has a diameter of around , with a tall inflorescence. The flowers grow on one side of a single slender, hairless stalk that emanates from the centre of the leaf rosette. White or pink in colour, the five-petalled flowers produce , light brown, slender, tapered seeds.
In the winter, ''D. rotundifolia'' produces a hibernaculum to survive the cold conditions. This consists of a bud of tightly curled leaves at ground level.
