About
Clematis 'Côte d'Azur' is a deciduous perennial that typically reaches heights of 1 to 1.2 meters. It features elliptical green foliage and bears clusters of tubular, light-blue flowers measuring approximately 2.5 centimeters in length. Each flower has a lighter central stripe and is surrounded by slightly twisted outer sepals, which frame creamy-white anthers. The blooms emerge on long stalks from the leaf axils and are produced from midsummer through early autumn.
