Perennials for Sun

combo2lr_pcojenThese types of flowers are hardy to our area.  So, you can plant them once and enjoy them for years to come.   Perennials generally bloom hardest in one particular season.   But, they may overlap into the next season (ex. late spring into summer).    Ideally, you should include spring, summer, and fall blooming plants so that you will have color in your garden all season.  To help you with this effort, we've organized the flowers below by the season in which they BEGIN blooming...Spring, Summer, or Fall

Note:  See our groundcovers section for perennial groundcovers for sun.
