The exquisite large star-shaped, pure white robust flowers some 12-14cm across, with red anthers, are formed from May through to July, clothing the plant from base to tip. Reliably repeat flowers into September. Guernsey Flute would make a wonderful addition to a patio, in a container, or in the mid to front of a flower border, where it’s longevity of individual blooms and successive flowers can be fully appreciated. This exceptional clematis has an unusual but endearing trait of holding, just open flower buds, for an extended period, almost like a champagne flute, hence the use of ’flute’ in its name. When flowers mature they open fully flat, with pointed sepals and of generous proportions. Possibly the most robust flower of any white form of large flowered hybrid clematis.
