Silene conica is a species of flowering plant in the family Caryophyllaceae known by the common names striped corn catchfly[1] and sand catchfly.

[2] It grows in dunes and sandy soils and is widespread in Europe and western Asia.

[3] It has an annual life history and produces self-compatible hermaphroditic flowers and occasional male-sterile flowers (i.e., gynomonoecy).

Like other members of Silene section Conoimorpha, S. conica is readily recognizable based on its bright pink petals and the prominent, parallel veins on its calyx.

[4] In contrast to most flowering plants, S. conica appears to have a very rapid rate of mitochondrial mutation, and has the largest mitochondrial genome (11.3 Mb) ever identified.
