An ornamental climber, supporting itself by means of aerial roots. White flowers are borne in large, flattened cymes. Leaves heart-shaped, dark green, turning yellow in autumn. Though slow-growing (0,5 m of annual growth), it eventually reaches 6 m. Superb species for partially shady or shady positions, walls, tree trunks and as ground cover. Best in moist and acid soils. Pruning: moderate, only when needed.
