Never failing to impress, Clematis 'Barbara Harrington' is a vigorous large-flowered clematis variety which gets covered with a profusion of large, 5 in. (12 cm), glowing purple-red flowers, with elegantly recurving sepals, and contrasting golden stamens. Flowering occurs from early-mid summer to early fall. This clematis is ideal to grow over fences, trellises or through shrubs.

  • Thrives in moist, well-drained soils, in full sun or part shade. Ideally, Clematis prefer having their 'heads in the sun and their feet in the shade'. Keep the roots cool and shaded by other plants or add a layer of pebbles or flat stones at the base. Afternoon shade is appreciated in hot summer areas.
  • Hardy, it is incredibly free-flowering and can quickly grow up to 8-10ft. long (240-300 cm).
  • Excellent choice for trellis and can be trained to climb a wall, fence or arbor.
  • This Clematis belongs to the third group of Clematis – a group including Clematis which flower in late summer on growth made in that season. They should be pruned in late winter or early spring and require 'hard pruning': simply cut back the stems to a pair of strong buds about 1ft. (30 cm) above ground level before growth begins in early spring.
  • Toxic to dogs, toxic to cats, toxic to horses.
