White campion (white cockle)

Silene latifolia Poir.
Caryophyllaceae (Pink family)

Life cycle
Annual, biennial or short-lived perennial.

Leaves
Seedling leaves initially develop from a basal rosette. Basal leaves are attached to the stem by petioles; stem leaves are without petioles. Leaves are opposite, softly hairy with a grayish tinge, and lance-shaped to oval with a pointed tip and smooth to slightly wavy leaf margins.

Stems
Soft, hairy stems are erect or semierect at maturity, and up to 3 feet tall. Stems
have swollen nodes and often branch at the base.

Flowers and fruit
Male and female flowers are produced on separate plants. Flowers have five showy, white petals, each with a deep V-shaped notch at the tip. Just below the petals are fused and inflated sepals that create a balloonlike appearance. Fruit are light brown, vaseshaped capsules with 10 teeth at the open end. Each capsule contains numerous brown to gray, kidney-shaped seeds.

Reproduction
Seeds and root fragmentation.
