Rouge Cardinal Clematis
Clematis 'Rouge Cardinal'Clematis ‘Rouge Cardinal’ is a striking and dramatic clematis variety known for its bold crimson-red flowers with a velvety sheen. Blooming from midsummer into early fall, it adds a rich, luxurious splash of color at a time of year when many vines have finished flowering. Each bloom measures approximately 4–6 inches across and features contrasting creamy-yellow stamens, creating a beautiful focal point against the deep green foliage. Its vivid coloring makes it especially stunning when planted near lighter or pastel-toned plants, where the blooms can truly stand out.
This vigorous and dependable climber thrives on trellises, arbors, pergolas, and fencing, easily filling vertical spaces with lush growth and abundant flowers. It performs best in full sun to partial shade, though like many red clematis varieties, its flowers retain their deepest color when provided with some afternoon shade. Known for its strong performance and long blooming season, ‘Rouge Cardinal’ is an excellent choice for gardeners seeking a bold, high-impact clematis that remains easy to care for and prune.
