Common Sundew

<em>Drosera rotundifolia</em>, the common sundew, is a carnivorous flowering plant in the family Droseraceae, order Caryophyllales. It has a broad distribution spanning Europe, Asia, and North America, typically growing in sphagnum bogs, wet heathlands, and other nutrient-poor, acidic wetland habitats where it compensates for low soil nutrient availability by trapping and digesting insects. The round leaves bear red, glandular tentacles tipped with sticky mucilage that immobilize prey, which is then digested by enzymes secreted from the leaf surface. <em>Drosera rotundifolia</em> produces small white flowers on a slender scape, pollinated by insects. It plays a minor but ecologically interesting role in controlling insect populations within its boggy habitat. Biological traits including typical individual lifespan, precise leaf dimensions, and detailed prey composition remain poorly documented. The species is assessed as Vulnerable by the IUCN, reflecting significant population declines across much of its range driven primarily by drainage and destruction of peatland habitats, atmospheric nitrogen deposition, and climate change altering the hydrology of bog ecosystems. Effective peatland conservation is critical for the long-term survival of this species.
