General Description

Unassuming soft, light gray green foliage of the sea campion is a pleasant backdrop to the wispy stems with white flowers in summertime. This semi-evergreen mounding perennial that is low and sprawling is native to the coastal regions of northern and western Europe. It has a deep root system that sustains the plant in the sandy, rocky landscape.

Its leaves are fleshy and oval with minute hairs, making it a light green with grayish hues. In summer, wiry stems that are either held upright or trailing hold delicate white flowers. The rounded V-shaped petals are held by a plump, globe-like calyx that is mauve colored with darker mauve veins. Pollinated by butterflies, seeds will develop and scatter in surround soil; the dried calyx body becomes tan and remains, adding interest among the leaves in fall and winter.

Grow sea campion in full to partial sun in moist, freely-draining soils that are not acidic in pH. Ideal for beachside gardens as well as rockeries and nooks in dry mortar retaining walls, it will haphazardly reseed itself, thus making it good for naturalizing. A double-flowered cultivar, 'Flore Pleno' has white blossoms and 'Druett's Variegated' foliage is gray green with creamy light yellow margins.
