Silene latifolia, commonly known as white campion, is a perennial wildflower native to Europe and western Asia. It is distinguished by its white, often night-scented flowers and its inflated, veined calyx, which gives the blooms a lantern-like appearance. Unusually, the species has separate male and female plants, making it a classic example of plant sexual dimorphism studied in genetics. The flowers open mainly in the evening to attract nocturnal pollinators, especially moths, setting Silene latifolia apart from many other meadow flowers that rely on daytime insects.
