Drosera rotundifolia, the round-leaved sundew, roundleaf sundew, or common sundew, is a species of carnivorous flowering plant that grows in bogs, marshes and fens. One of the most widespread sundew species, it has a circumboreal distribution, being found in almost all of Europe, all of Siberia, large parts of North America, Korea and Japan but is also found as far south as eastern China, the Philippines, and into the Southern Hemisphere in New Guinea.
Description
The leaves of the common sundew are arranged in a basal rosette. The narrow, hairy, 1.3-to-5.0-centimetre (0.5 to 2.0 in) long petioles support 4-to-10-millimetre (0.2 to 0.4 in) round 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 3 to 5 centimetres (1.2 to 2.0 in), with a 5-to-25-centimetre (2 to 10 in) 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 1.0-to-1.5-millimetre (0.04 to 0.06 in).
