Clematis x durandii differs from most clematis in that it is not a climbing variety, so it is the perfect choice for garden borders. It can also still be trained up trellis or obelisks using ties, making it truly versatile. The stunning indigo blue flowers feature 6 to 8 narrow, twisting sepals as well as golden yellow anthers in the centre, adding an excellent contrast to other plants in your border. Clematis x durandii is straightforward to grow, blooming between June and September and has been awarded an Award of Garden Merit by the Royal Horticultural Society. Height: 2m (6'). Spread: 1m (3'). Pruning group: 3.
