Comments

The long-tubular, clavate calyx enclosing the unusually long carpophore helps to distinguish Silene armeria. It is an occasional and adventive garden escape.

Silene armeria

Silene armeria, commonly known as the Sweet William Catchfly, is a plant of the family Caryophyllaceae. Originally a native of Europe, it has become widespread in the USA. A small-growing form is known as Dwarf Catchfly. The name comes from the way in which small insects are trapped by the sticky sap exuded onto the stem. However it is not currently regarded as a carnivorous plant, though it has been identified as a carnivorous plant in the past.[1]
