Petals are deeply cut into four linear segments. This species requires a moisture-retentive soil and full to partial sun for best results. Lychnis cognata is a species native to northeastern China and Korea where it grows in open woodland, along the edges of woodland and grassy meadows. It grows to a height of 40 to 100 centimetres. Stems are few, however, increased bushiness can be achieved by removal of the growing shoot early in the season, and after about three years bushy clumps will result.
Stems are bristly-hairy or glaborous and have ovate to elliptical leaves.
Chinese Delight' is a recent introduction of the Devonian Botanic Garden. It will be commercially available in a couple of years. This species is small with dark green, linear or linear-lanceolate leaves and bears white flowers in loose corymbs. It appears to thrive best in the full sun or partial shade on a moisture-retentive soil. This species is a useful addition for the front of a bed or border.
