These shrubs are best used among evergreens, where they can make a show when in flower, then blend back in with other greenery later on. Bloom season coincides with that of late-spring bulbs such as tulips and Dutch iris. Pruned shrubs after bloom. With low or medium growing kinds, cut some of oldest stems to ground every other year. Pruned tall growing kinds severely by cutting back wood that has flowered. Cut to outward-facing side branches.Deutzia gracilis
