In the garden

Silene dioica 'Richmond' is a herbaceous perennial in the Caryophyllaceae, native to parts of Belgium. It is valued for its pink–red flowers that appear from June to September and for its mid-border height of roughly 0.5 m. In UK terms it carries an H7 rating (fully hardy), and it also falls within USDA hardiness zones 5–9. Choose a site in full sun or partial shade on a south, east or west aspect; avoid deep shade. The plant adapts to sandy, loamy or clay soils across a range of pH levels (acidic to alkaline) but performs best where the ground remains moist yet drains freely. It tolerates both sheltered and more exposed locations, so it will withstand breezy garden edges as well as more protected beds. Planting in groups suits its suggested uses: mixed herbaceous borders, wildflower gardens and naturalising schemes. At around 0.5 m tall it sits well between lower groundcovers and taller perennials, providing a steady run of colour from early summer into early autumn. Positioning it where its June–September display can be seen close to paths or lawn edges makes the most of the seasonality of the flowers.
