Clematis ‘Rouge Cardinal’ is a dramatic and widely admired variety, valued for its deep, насыщated colouring and strong flowering performance. It is particularly suited to gardeners who want to introduce richness and intensity to vertical planting areas during summer.

This variety produces large, velvety blooms in a dark crimson-red shade, often highlighted by contrasting pale stamens at the centre. Flowering is generous and long-lasting, typically from mid summer into early autumn, offering bold colour when many other climbers begin to fade.

‘Rouge Cardinal’ grows as a vigorous climbing plant, reaching approximately 2 to 3 metres once established. It performs beautifully on trellises, arches, and fences, and can also be trained through shrubs where its flowers stand out with striking effect.

For best results, plant in full sun to light shade in fertile, well-drained soil that remains evenly moist. Like most clematis, it benefits from cool roots and sunlit upper growth. Mulching or planting low-growing companions around the base helps create favourable growing conditions.

This clematis flowers on new growth and responds well to a stronger prune in late winter or early spring. Pruning encourages vigorous fresh stems and abundant flowering throughout the season.

For intense summer colour with a luxurious garden presence, ‘Rouge Cardinal’ remains an outstanding and dependable choice.
