Lychnis flos-cuculi

ragged robin

Product Image
A wonderful British native wildflower for wet meadows, bog gardens, or suitably moist areas of the garden. Upright with branching stems bearing lance-shaped leaves, ragged robin dazzles with terminal clusters of star-shaped, deep rose-pink flowers, narrowly dissected to which insects flock in late spring and early summer.

How to care for Lychnis flos-cuculi:

Lychnis thrives in well-drained soil, preferably in full sun or partial shade. Plant in a location where it can receive at least six hours of sunlight daily for optimal flowering. Before planting, enrich the soil with organic matter to ensure good soil health and improve heavier or lighter soils.

Once established, this hardy perennial benefits from regular watering during dry spells to keep the soil consistently moist. Deadhead spent flowers to prolong blooming and trim back the plant after flowering to encourage a tidy shape and prevent self-seeding.

In late autumn or early spring, cut back the foliage to ground level to prepare for new growth.

Sowing instructions:

Surface-sow directly onto trays filled with good seed compost in March or April, and maintain temperatures around 20C. When seedlings are large enough to handle, pot them up individually and grow them on. Gradually harden off before planting outside after risk of frost. Autumn-sown seedlings (August to October) should be overwintered in a coldframe before planting out the following spring.
