September is an ideal time to start creating stunning displays for next spring and summer. Even though this season isn’t over, sowing hardy annuals and perennials this month sees them put down strong roots before winter and reward you with earlier blooms next year.
A wide variety of hardy annual and perennial flowers can be sown in September to ensure your flower beds, borders, and containers are flooded with gorgeous color and texture. Hugely popular plants like sweet peas, lupines, larkspur, coneflower, and columbine are among some of the best flowers to plant in September.
