Flowering shrubs include butterfly bush, rose of Sharon, hydrangeas, summersweet and potentilla. All of these shrubs bloom during the summer and are easy to care for.
Butterfly bush has a long growing season and has purple, pink or white blossoms similar to lilacs. Roses of Sharon produce an abundance of tropical-looking pink, lavender or white flowers during the hottest part of the year. Known for big blooms and attractive foliage, hydrangeas grow in sun or shade. Summersweet flourishes in shady spots and produces sweet-smelling white or pink blossoms. Blooming from spring to late fall, potentilla bears flowers in red, yellow, orange or white.
