Rose Campion Growing Guide

Silene coronaria (Synonym Lychnis coronaria)

Crop Rotation Group

Miscellaneous ●

Soil

Fertile, well-drained soil enriched with compost.

Position

Full sun to partial shade.

Frost tolerant

Yes, rose campion is a hardy short-lived perennial that can tolerate winter cold to -34°C (-30°F).

Feeding

Mulch over the plants’ root zones with rich compost just as new growth emerges in spring. Drench plants with a liquid fertiliser after cutting them back in midsummer to support the growth of new leaves.

Spacing

Single Plants: 30cm (11") each way (minimum)
Rows: 30cm (11") with 30cm (11") row gap (minimum)

Sow and Plant

Start rose campion seeds indoors in late winter, or use winter sowing techniques to start them outdoors while the weather is still cold. Set out home grown or purchased seedlings as soon as the soil warms in spring. Young plants need water when they are actively growing. A surface mulch suppresses weeds while making the plants look more attractive. To propagate rose campion, look for seedlings with felted gray leaves growing near the mother clump in spring. Carefully lift individual seedlings from beneath, keeping soil packed around their roots, and gently transplant to a new location. In containers, use one plant per 35 cm (14-inch) wide pot. Upright rose campion combines well with pansies and other small annual flowers.

Notes

Individual plants live only a year or two, and are replaced by volunteer seedlings. When well pleased with its site, rose campion will reseed for many years, with new seedlings appearing in autumn and spring. Cutting back the plants by one third their size in midsummer improves the appearance of the luminous foliage. The species blooms a rich dark pink, but selections are available with white or pale pink flowers.

Harvesting

Rose campion is slow to establish and will not bloom well until its second year in the garden. After that, the plants put on a brilliant show every summer, with magenta to white blossoms against felted gray foliage. Gather stems for use in cut arrangements as you need them, or weave the long stems into garlands. Cutting old blossoms will stimulate modest reblooming. Allow a few spikes to stay on the plants until they shed mature seeds.
