Ornate, heavily dissected, evergreen leaves provide a superb contrast with the glistening white flowers from early spring. Clematis x cartmanii ' Avalanche' boasts some of the largest blooms of the evergreen clematis, with flowers up to 4cm in diameter. The non-clinging stems have a scrambling habit which is ideal for wandering through borders among established shrubs, or can be trained onto an obelisk for a show-stopping spring display.
