Clematis cartmanii ‘Sweet Hart’ is a charming, compact climber that bursts into masses of creamy white, star-shaped flowers from late spring to early summer, often with a second flush in early autumn. Perfect for small spaces, containers, or growing through shrubs, it thrives in full sun to part shade with its roots kept cool in moist, well-drained soil. Easy to train and lightly scented, it adds romance and vertical interest.
