A charming cottage garden perennial with bright red-pink flowers and heart-shaped petals that bloom over a long season. It self-seeds readily and attracts pollinators, making it excellent for informal borders and woodland edges.

Why grow it

Red campion offers a reliable source of nectar and pollen for a range of pollinators over an extended bloom period, making it useful for supporting beneficial insects in gardens and edges. Compared to other Silene species, it tolerates partial shade well and establishes readily from seed, which can reduce propagation effort in informal plantings. Its preference for moist, well-draining soil and moderate fertility distinguishes it from some campion relatives that thrive in leaner conditions.

Watch out for

Red campion can self-seed prolifically in favorable conditions, potentially appearing in unexpected garden locations over successive years. Male and female flowers appear on separate plants, so establishing both sexes may be necessary if reliable seed production is desired. In areas with heavy clay soils or poor drainage, plants are more prone to fungal issues, particularly in humid seasons.
