Some flowering shrubs, like the hydrangea, are deciduous and will lose their leaves during the winter months. Others, like holly shrubs, are evergreen and will add a splash of color to the landscape long after they have flowered.
Some ornamental flowering shrubs do well planted in groups as a hedge; the Autumn Twist azalea can reach heights of up to 6 feet, and erupts in white and purple flowers in the spring, summer and fall. Others can make excellent stand-alone pieces, framing entryways, deck stairs or the corners of buildings.
Some flowering ornamentals sport the flowers as their main feature of interest. Azaleas and hydrangeas both come in a variety of different colors with both single or double blossoms. Other flowering shrubs, such as the holly, have insignificant flowers but showy fruits that develop after the flowers fall.
Different ornamental shrubs flower at different times; when creating a feature with mixed variety, taking this into consideration can ensure that something is always in bloom. Most hydrangeas flower in the late spring through the early summer; the star magnolia blooms in the late winter and early spring. Some, like the Japanese witch hazel, even flower in the winter.
