There was some pretty stiff competition, but this lovely clematis was voted  the winner of the coveted RHS Chelsea Plant of the Year 2016. The judges loved  the soft yellow flowerheads, which sometimes have a faint pink blush to the  edges of the pointed sepals. These nodding gems appear over a relatively  long period too - usually from early to midsummer, and then with a second  flush in early autumn.
 Clematis koreana Amber is not too big, so is perfect for training up an  obelisk, and can even be grown in a large patio pot. 
                                        How to care for Clematis koreana Amber ('Wit141205') (PBR):
                                         To avoid dry conditions, and to ensure good soil contact around the rootball, we advise planting climbers at least 30cm (12in), and preferably 45-60cm  (18-24in) away from the base of a wall or fence. An even larger distance should be maintained when planting climbers beside an existing tree or shrub.
 Clematis need their roots to be kept cool and moist, so plant the base of these climbers in light shade or provide shading with other plants or a dressing of  of pebbles. 
 No routine pruning is necessary. If the spread of the plant needs to be restricted prune immediately after flowering, cutting back overlong shoots to healthy buds.
 Apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the base of the plant in early spring.
