No, generally you do not have to replant black-eyed Susans every year. Most varieties of black-eyed Susans are perennial, meaning they naturally return year after year.
Understanding Black-Eyed Susan Growth Habits
While the majority of black-eyed Susans are perennials, some types might be short-lived. However, even with these shorter-lived varieties, the need for yearly replanting is often minimized because many black-eyed Susans self-sow readily. This natural process ensures a continuous presence of these cheerful flowers in your garden without requiring manual replanting each spring.
These plants are known for being low-maintenance and begin opening their vibrant blooms in early summer, continuing to flower abundantly until the first fall frost arrives.
