The vigorous growth and large burgundy-purple flowers of the Rouge Cardinal Clematis make it a must for any garden. Growing to 6 to 12 feet tall, Rouge Cardinal Clematis was born to climb and develops sumptuous burgundy-purple flowers 4 - 6 inches across on a framework of green foliage. It blooms from early summer until the fall.
A vigorous clematis, Rouge Cardinal Clematis is ideal for growing up a pergola, obelisk or trellis. It is cold hardy and suitable for growing in zones 4 to 11. It can also be grown through a host tree. This perennial vine often attracts hummingbirds when in bloom.
Rouge Cardinal Clematis Care
The Rouge Cardinal Clematis grows happily in full sun to partial shade. For best performance, plant it in fertile, moist and free-draining soil. Water well on planting and until established. Once mature, irrigate during dry spells to keep the soil moist. Apply a low-nitrogen fertilizer in the spring.
Keep the roots cool by shading them with other plants. Hard prune all stems back to 1 foot in early spring, cutting just above a visible pair of buds. Provide support and tie in as necessary.
Rouge Cardinal Clematis Spacing
As a vigorous climber, the Rouge Cardinal Clematis can reach 6 to 12 feet tall and 3 to 4 feet wide. If using multiple plants to cover a large wall, a spacing of 3 to 4 feet will allow them to fill in over time.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
- When to Prune
- Late winter to early spring, before new growth starts
