The flowers of the white campion are quite small, measuring approximately 2.5 cm in width. Each radially symmetrical bloom has a white or green-veined, inflated calyx that is surrounded by five, white or pink, deeply notched petals. The male flowers of this species have a less-inflated, ten-veined calyx and ten stamens. The female flowers have three styles and exhibit a largely inflated, 20-vined calyx. Flowers are singularly along the length of the stem.
The capsule-like fruit is vase-shaped, many seeded, and grows within the largely inflated calyx of the female flower.
The leaves of this wildflower measure 4-10 cm. in length, and are hairy, thin and lanceolate-to-ovate in shape. They are arranged in an opposite fashion along the length of the stem.
The white campion grows best in fields, along roadsides, or around waste areas.
The inflated calyx is actually a structure of fused, inflated sepals.
The white campion species has a European origin and, as indicated above, is not a perfect flower. The female and male flowers bloom at night and are pollinated by moths.
Other names attributed to this flower include evening lychnis and white cockle.
