Pleasantly fragrant, Clematis 'Cezanne' is a compact, deciduous, climbing perennial, which gets covered with a profusion of large, star-shaped, sky-blue flowers, up to 5-6 in. (12-15 cm), with broad and overlapping petals surrounding a small boss of creamy-white stamens. Flowering from late spring to early fall, this large-flowered clematis is ideal for small gardens, and containers and looks terrific when combined with small shrubs.
