Clematis ‘Rouge Cardinal’ Description

Clematis ‘Rouge Cardinal’ is a vigorous late-flowering deciduous climber with large single blooms in a deep velvety crimson shade. Creamy-white filaments and reddish-brown anthers create a contrasting centre. Flowers appear from early or midsummer into early autumn on stems produced during the current season. Growing around 2.5 to 4 metres high with a relatively narrow spread, it works well on fences, wall trellises, arches and large obelisks. Plant in sun or partial shade in fertile, moisture-retentive but well-drained soil, keeping the base shaded and cool. It is hardy and dependable in Ireland. Prune all old stems back to healthy buds approximately 30 to 50cm above ground in late winter or early spring.
