The genus is named after J. D. van Deutz, an Amsterdam burgher. It contains some 50 species mostly from eastern Asia and the Himalayas. Only two grow in North America and Mexico.
Deutzia magnifica is a cross between Deutzia scabra and Deutzia vilmorinae. It is a shrub about 2.5 m (8 ft) high, of severe, upright habit, with thick, brown branches. The leaves are longish-lanceolate, 4 to 6 cm (1½ to 2¼ in) long, on young shoots often as much as 14 cm (5½ in) long, finely toothed on the margin, rough, grey-green below, bright green above and hairy. Theare white, 2.5 cm (1 in) in diameter, and borne in dense panicles from May to June. Commonly grown are the varieties latiflora with white, single flowers up to 2.5 cm diameter, eburnea with single, bell-shaped flowers in loose panicles, and longipeta-la with white, long-petalled flowers.
Deutzia magnifica is propagated by means of seeds sown in March under glass. Garden varieties are propagated by vegetative means, generally by softwood summer cuttings. Deutzia does best in good gardenwhich does not become unduly dry and in full sun. It tolerates light shade but not on soils that dry out, though it will not flower so profusely. The shrubs should be thinned out occasionally by removing old shoots from the centre. They are useful for parks and small gardens, particularly when planted together with , cotoneasters, quinces or taller conifers as a backdrop.
