Vigorous and durable, award winning Clematis 'Purpurea Plena Elegans' has masses of distinctive, very double, purple pink flowers, up to 5cm wide. Slow to open, the glorious small blooms last about 2 weeks before their outer sepals fall away. Their inner pompon lasts another week at least. Blooming profusely over a very long season, this Clematis viticella hybrid resists clematis wilt and does very well if left unpruned for several years.
