Barbara Jackman Clematis

Clematis ‘Barbara Jackman’ is a deciduous, large-flowered climbing hybrid with blue flowers marked by a crimson or petunia-red bar. Its first display comes in spring, followed by another crop later in the season on new growth. The vine can be trained over a trellis, fence, shrub, or large container support. ## Flowers and growth The [International Clematis Society cultivar profile](https://www.clematisinternational.com/page31.html) describes rounded, usually 4–5 inch flowers, with blue-purple margins that fade while the bar keeps its color. It reports that the plant can reach 3 m (10 ft) or more, though it can be kept lower, and that it finishes with ornamental seedheads. The catalog’s existing height range remains a practical guide; the source gives no defined spread, so width remains indeterminate. ## Siting Use a sturdy support and allow room for stems to climb and branch. The vine can also grow in a tub, where the flowers and later seedheads remain close to a path or seating area. ## Maintenance This spring-flowering hybrid carries a later crop on new wood. If it needs a substantial trim, the Society recommends doing so as the first spring bloom finishes; a winter hard prune would remove the early flowering growth.
