Bladder Campion (Silene vulgaris) is a hardy and distinctive native UK wildflower, named for its inflated, bladder-like calyx that gives its small white flowers a unique appearance. This perennial species is commonly found in grasslands, road verges, field margins, and dry banks, thriving in poor, well-drained soils. Its upright, branching stems and delicate flowers add charm and structure to wildflower meadows.
Bladder Campion is tolerant of dry, calcareous, and sandy soils and performs well in full sun. The flowers are lightly scented and attract a range of pollinators, including bees and moths, making it a valuable component in wildflower mixes designed for biodiversity and habitat creation.
