Never failing to impress, Clematis ‘Rouge Cardinal’ is a vigorous large-flowered clematis variety that gets covered with a profusion of large, 4-6 in. (10-15 cm), glowing velvety crimson flowers, with elegantly recurving sepals, and contrasting creamy stamens. Flowering occurs from early-mid summer to early fall. Its foliage of trifoliate medium green leaves darkens as the summer progresses. This clematis is ideal to grow over fences, trellises, or through shrubs.

  • Thrives in moist, well-drained soils, in full sun or part shade. Ideally, Clematis prefer having their ‘heads in the sun and their feet in the shade’. Keep the roots cool and shaded by other plants or add a layer of pebbles or flat stones at the base. Afternoon shade is appreciated in hot summer areas.
  • Hardy to zones 4-11, it is incredibly free-flowering and can quickly grow up to 6-12 ft. long (180-360 cm).
  • Excellent choice for trellis and can be trained to climb a wall, fence, or arbor.
  • This Clematis belongs to the third group of Clematis – a group including Clematis which flower in late summer on growth made in that season. They should be pruned in late winter or early spring and require ‘hard pruning’: simply cut back the stems to a pair of strong buds about 1ft. (30 cm) above ground level before growth begins in early spring.
  • Toxic to dogs, toxic to cats, toxic to horses.

As climbers, Clematis are unsurpassed in their long flowering presence, their rich diversity of flower shapes, and their wide array of colors and tolerances in terms of exposure and climate. It is no wonder they are so popular! From tree huggers to container varieties, there is a Clematis for every garden and flowers for almost every month of the year! Members of the Ranunculaceae family, they include more than 300 species and hundreds of hybrids. They create year after year a ravishing colorful show in the garden whether solely trained on walls, arbors, or trellises, or grown in association with other climbers. They are divided into 3 groups which determine how they should be pruned. Regular pruning of Clematis is important as it promotes strong growth and flowering as well as a harmonious plant. If left unpruned, Clematis can turn into a mass of tangled stems with a bare base and flowers well above eye level.
