Landscape Attributes

Rosemoor Clematis is a multi-stemmed deciduous woody vine with a twining and trailing habit of growth. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition.

This is a relatively low maintenance woody vine. It is a Type 3 clematis; each spring it should be pruned back to within a few inches of the ground, as it flowers on new wood of the season. It is a good choice for attracting bees and hummingbirds to your yard. It has no significant negative characteristics.

Rosemoor Clematis is recommended for the following landscape applications;

  • Accent
  • Hedges/Screening
  • General Garden Use
  • Container Planting

Planting & Growing

Rosemoor Clematis will grow to be about 8 feet tall at maturity, with a spread of 24 inches. As a climbing vine, it tends to be leggy near the base and should be underplanted with low-growing facer plants. It should be planted near a fence, trellis or other landscape structure where it can be trained to grow upwards on it, or allowed to trail off a retaining wall or slope. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years.

This woody vine does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.

Rosemoor Clematis makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
