Atocion armeria, commonly known as Sweet William catchfly, is a species of plant in the family Caryophyllaceae. Originally a native of Europe, it has become widespread in the United States. A small-growing form is known as a dwarf catchfly. The name comes from the way in which small insects are trapped by the sticky sap exuded onto the stem. Although it has been identified as a carnivorous plant in the past, it is not currently regarded as such.[1]

The blooming period in British Isles is from June to October. Clusters of pink or lavender flowers arranged somewhat openly or compactly at the end of stems. Stem hairless (glabrous) or slightly hairy with sticky areas, especially just below the cluster.
