Culture
Grow in fertile, medium moisture, well-drained soils in full sun to part shade. Roots should be kept cool, shaded and uniformly moist. Mature plants have some drought tolerance. Bloom occurs on the current year’s growth. Plants should be cut back hard (to 8-12” from the ground) to strong leaf buds in late winter to early spring. Plants generally need an adequate supply of nutrients during the growing season to support the rush of growth.
Noteworthy Characteristics
Clematis × triternata is a hybrid between C. flammula and C. viticella.
Genus name comes from the Greek word klematis which is an old name applied to climbing plants.
‘Rubromarginata’ is a vigorous vine that typically grows to 10-12’ and features masses of small, very fragrant, 4-tepaled, white flowers (1.5” wide) in a long July to September bloom. The tepals are narrow, and are flushed with rose-lilac margins as the cultivar name suggests. Branches are clad with simple to bipinnate dark green leaves.
Problems
Clematis wilt is a potentially fatal fungal disease that can affect any clematis, but large-flowered, hybrid varieties are the most susceptible. Powdery mildew, leaf spots, rust and viruses can also be problematic. Potential insect pests include aphids, vine weevils, slugs/snails, scale and earwigs. Watch for spider mites.
Uses
This vigorous clematis is a compact variety that fits well into small spaces and city gardens. It can be trained to climb walls, trellises, fences, pergolas, arches or other stationary structures. It can also be planted to sprawl over and through shrubs or to scramble along the ground. Plant near a patio for enjoyment of the fragrant flowers.
