Perennial Bloom Times for Sun

One of the greatest design challenges when planning perennial gardens and mixed borders is selecting the right plants to provide continuous color throughout the season. You can create a never-ending cycle of color by using the right sun perennial combinations . The table below guides you in selecting the appropriate perennials so that your sunny spot is splashed with color from April until October. Since bloom times can vary and are affected by temperature and rainfall, the plants are categorized by the calendar month when they usually bloom. Flower color also is listed to assist in planning.
