Silene latifolia, commonly known as white campion or bladder campion, is a species of flowering plant belonging to the family Caryophyllaceae. It is a herbaceous perennial native to Europe and introduced to various other regions across the globe, including North America and Australia.
White campion typically grows up to a height of one to three feet (30-90 cm) and has an erect, branching stem with soft, hairy leaves. It produces distinct white flowers with five deeply notched petals. The flowers are arranged in clusters at the end of the stems, and they typically bloom from late spring to summer.
This plant is known for its adaptability and invasive tendencies. It thrives in a variety of habitats, including grasslands, open woodlands, disturbed areas, and gardens. It can also tolerate a wide range of soil types and climates, making it a successful colonizer in many regions.
White campion is dioecious, meaning that male and female flowers occur on separate plants. Its name "bladder campion" is derived from the shape of the seed capsules, which resemble small bladders. These capsules contain numerous seeds, which are dispersed by wind or by adhering to animals' fur or clothing.
Although white campion is considered a weed in many parts of the world, it has also been used for certain medicinal purposes in traditional medicine. Extracts from its roots have been utilized to relieve urinary tract problems and coughs, among other ailments.
Despite its potential benefits, white campion's invasiveness and ability to outcompete native species have led to its classification as an invasive plant in some areas.
