Flowers have colorful foliage and bright blooms to light up the landscape. There are many flowers to choose from to provide a long-lived and unfussy garden. Perennial flowers are a satisfying choice because they come back each year. Perennial flowers can also be drought- and deer-tolerant, making for a hardy and robust garden. Annual flowers are not long-lived, but they provide a seasonal splash of color and texture in the landscape.
