Clematis Rouge Cardinal

Clematis Rouge Cardinal is one of the most iconic large-flowered clematis varieties, celebrated for its exceptional colour, texture, and reliability. Bred for both performance and visual impact, this variety produces large, velvety sepals in a deep, regal crimson-red that retains its intensity even under full sun. Each bloom is accentuated with a crown of creamy-brown stamens, creating a striking visual contrast and an elegant jewel-toned effect that elevates any garden display.

Awarded the prestigious RHS Award of Garden Merit in 1968, Rouge Cardinal is recognised for its superior flowering ability, vigorous growth, and resilience in a variety of garden conditions. It belongs to Clematis Group 3, meaning it benefits from hard pruning in early spring to encourage fresh growth and maximise flowering potential. Despite its bold blooms, its compact habit ensures it fits seamlessly into smaller spaces while still delivering dramatic vertical impact.

Clematis Rouge Cardinal grows to a height of approximately 2–2.5 metres, with a spread of 1–1.5 metres, making it suitable for both patio containers and garden borders. Each flower measures around 12–15cm across, featuring velvety crimson petals with creamy-brown central stamens. Its compact yet vigorous habit ensures excellent vertical coverage without overwhelming neighbouring plants. Flowering occurs from midsummer through late autumn, providing a long-lasting display of jewel-toned colour. This variety is particularly striking when planted against pale walls, fences, or neutral backgrounds, where the deep red blooms create maximum visual impact. Its adaptability to containers, trellises, and garden structures makes it an ideal choice for both modern and traditional garden designs.
