About
Silene latifolia, commonly known as white campion, is a dioecious flowering plant in the family Caryophyllaceae, native to most of Europe, Western Asia and northern Africa. It is a herbaceous annual, occasionally biennial or a short-lived perennial plant, growing to between 40–80 centimetres tall. It is also known in the US as bladder campion but should not be confused with Silene vulgaris, which is more generally called bladder campion.
The appearance depends on the age of the plant; when young they form a basal rosette of oval to lanceolate leaves 4–10 cm long, and when they get older, forked stems grow from these, with leaves in opposite pairs. The flowers grow in clusters at the tops of the stems, 2.5–3 cm diameter, with a distinctive inflated calyx and five white petals, each petal deeply notched; flowering lasts from late spring to early autumn. The entire plant is densely hairy.
Where it grows
White campion grows in most open habitats, particularly wasteland and fields, most commonly on neutral to alkaline soils. Despite the wide array of conditions in which campion can thrive, it prefers sunny areas that have rich and well-drained soil. An example ecoregion of occurrence is in the Sarmatic mixed forests.
Uses
The Ojibwe people have traditionally used a root infusion of this plant as a cathartic, as documented in Huron H. Smith's 1932 ethnobotanical study of the Ojibwe Indians. Historical European folk medicine additionally attributed sedative properties to the plant, with infusions reportedly used for insomnia and anxiety, and leaf poultices applied to skin irritations and wounds.
