This semi-herbaceous clematis is a stunner. Its small, star-shaped, purple-blue flowers have a pretty ruff of creamy-white stamens, and they appear from midsummer. If left unsupported 'Blue River' will rifle through the border creating good seasonal groundcover, but it also looks smart draped over robust shrubs, or mounding as a beautiful specimen supported by pea sticks or brash.
Semi-herbaceous clematis need their roots to be kept cool and moist, so plant the base of these clematis in light shade or provide shading with other plants or a dressing of pebbles. In early spring cut back the previous year's stems to a pair of strong buds about 15-20cm (6-8in) above ground-level and apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the plant - again avoiding the immediate crown.
