In the garden
Centranthus ruber 'Coccineus' is a cultivated form of Centranthus ruber in the Caprifoliaceae, carrying a columnar upright habit and semi-evergreen foliage. Flowering runs from June to September, making it valuable where sustained seasonal colour is needed. Position it in full sun on free-draining chalk, loam or sand with neutral to alkaline pH; poor drainage will reduce its performance. It tolerates both exposed and sheltered situations, and is rated H5 (hardy) for UK gardens, so it will withstand typical winter conditions where soil does not remain waterlogged.

Use Centranthus ruber 'Coccineus' in cottage and informal plantings, gravel and coastal gardens, or placed towards the back of flower borders and beds where its upright stems can show through. It also fits wildlife-oriented schemes and mixed beds where long summer bloom is required. For best effect plant in groups or singles where its prolonged June to September flowering can provide a consistent display.
