Deutzias are a genus of about 60 species and a number of cultivars of shrubs. They are very garden worthy in terms of their flowering, but they can be a bit dull for the rest of the year as the shape of the shrubs is often a bit untidy, especially if they have not been pruned.
The flowers are carried in bunches and are either pink or white, and they are generally starry in appearance. They are often carried in great profusion, weighing down the branches. In some species they are fragrant. The flowers appear between mid-spring to mid summer depending on species.
Most are hardy and will come through a winter without protection. They will grow in most fertile soils, but prefer ones that are not too dry, so add plenty of well-rotted organic material when preparing the ground. They do best in a sunny situation. They should be pruned after flowering, cutting back the flowered shoots to a strong bud or shoot and removing about a quarter of the older wood at the base.
