The species
Silene flos-cuculi (syn. Lychnis flos-cuculi), commonly called ragged-robin, is a perennial herbaceous plant in the family Caryophyllaceae. This species is native to Europe and Asia, where it is found along roads and in wet meadows and pastures. In Britain it has declined in numbers because of modern farming techniques and draining of wet-lands and is no longer common. However, it has become naturalized in parts of the northern United States and eastern Canada.
