Description Flowering season: Late Spring, early summer. Approx height and spread: 3 m A genus of about 60 species of mainly deciduous shrubs native to the temperate regions of the northern hemisphere; mainly East Asia and North America. They usually have peeling bark and are grown for ornamental purposes, as a shrub border and for their fragrant flowers. Dwarf varieties are also available. The cultivated species are all quite similar and have light green, roughly elliptical leaves about 8 cm (3 in) long. They flower in late spring and early summer, and have 4-petalled white or cream flowers in loose clusters. The fragrance of the flowers strongly resembles that of orange blossom, hence the common name.
Growing Easy to grow they are moderately to very frost hardy, preferring moist, well-drained soil and a position in sun or light shade. They will, however, flower better in full sun, except for Philadelphus coronarius 'Aureus', which does better in part-shade. If grown on poor soil or if not pruned, some species can develop bare stems and few flowers. Thus regular feeding and watering are necessary throughout the growing season. If grown in pots, a loam-based compost is best. Prune after flowering. Propagate from seed or from softwood cuttings taken in summer or hardwood cuttings taken in autumn and winter.
