Mainly tall, sometimes arching, shrubs with richly-scented flowers in early summer. Although usually pure white and cup-shaped, some flowers have a maroon central blotch or are double-flowered. If you have a smaller plot, there are several low arching cultivars, ideal to spill over the front of a border. Plants have only one main spell of flowering in early summer. These shrubs are deciduous, shedding their leaves in winter.
