Clematis Rebecca™

One of the most effective Clematis is Rebecca™. It has massive 5- to 7-inch blooms in a shade of magenta-red seldom seen in nature that cover this climber not once but twice a season. Far more abundant than most others, they draw attention from all corners of the garden, especially during their late-summer encore, when little else is looking its best. So compact it can easily be grown in a container, this Raymond J. Evison introduction has the impact of a vine 5 times its size.

The single blooms simply electrify, beginning their first performance in late spring in most climates. Broad, overlapping petals with neatly ruffled edges and a central boss of creamy yellow anthers (resembling a startled eye, as well it might!) demand attention, nearly concealing the small green foliage and wiry brown stems altogether. This display continues for weeks, giving even the proudest rose an inferiority complex.

Rebecca™ rests during the warmest weeks of the summer, and repeats the show in very late season. Utterly magnificent, especially for a climber that reaches only 6 to 8 feet tall and scarcely 2 feet wide at maturity. Rebecca™ is classified as a large-flowered Clematis, and when you see these blooms, you may feel that you never really understood the term "large-flowered" so well before!

  • Care Instructions

    Early Spring:

    Fertilize with 5-10-10 when new growth reaches two inches.

    If you need to move a plant, transplant young vines now.

    Wait until new growth appears before removing dead or damaged stems and before pruning as required by variety: leave Group I Clematis alone; prune Group II plants lightly to shape and remove weak growth; cut Group III varieties back to 12 inches above the ground, or higher if you desire taller vines.

    If this is the first spring after planting, prune stems of all varieties down to the lowest pair of healthy buds to encourage strong growth and new stems.


    Continue feeding every month, alternating 5-10-10 with 10-10-10.

    Plant annuals at base of plants if unprotected by flat stones to allow for a cool root zone.

    Gently tie vines to supports as they grow.

    Late Spring:

    Mulch if desired but keep material away from crowns and stems.

    Water thoroughly if season is dry.

    Cultivate around vines with care as physical injury will cause wilting and death of injured stems.

    Continue to guide new growth by tying to supports as needed.

    Lightly prune Group I Clematis immediately after flowering to shape the vines if needed.


    Watch for signs of fungal wilt and remove and destroy affected plant parts if it occurs, then sterilize pruners with bleach solution.

    Group II Clematis may be pruned back by one-half after main flush of bloom to encourage strong growth and new flowers.

    Continue to water if conditions indicate.


    Check to be certain that the vines of Group I and II varieties are tied securely to supports to withstand winter wind and snow.

    Mulch if desired, keeping material away from the crown.

    If the season is dry, water well and deeply.
