Okay, so there are thousands of perennial plants to choose from to plant in your garden. But you want the one's with the longest flowering season, right...and why not? Who wouldn't appreciate more flowers in their garden?

I selected the perennial plants in the listing below based on my own experience growing them in Zone 8 of mid-Georgia using these criteria: dependability, ease of growing, overall performance, longevity, and long bloom period. Keep in mind that most nurseries, including Wilson Bros Gardens, carry perennials on a seasonal basis. 

Note:  Make sure to check USDA Zones to make sure they will grow in your area. Find Your Zone >
