  • It 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.
  • Quickly grows up to 6-8 ft. long (180-240 cm) and 3-4 ft. wide (90-120 cm).
  • Excellent choice for trellis, it can be trained to climb a wall, fence or arbor and is also well suited to containers. Combines beautifully with other climbers such as Roses.
  • 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.
