when do black eyed susans bloom

Black-eyed Susans typically bloom from early to mid-summer, around July, and continue blooming through to the first frosts in fall, often up to October. Some cultivars may start blooming as early as spring, and these flowers can bloom twice a year if their spent blooms are regularly deadheaded. Generally, they bloom for 4-6 weeks at the height of summer but can last longer with proper care and conditions such as full sun exposure and well-drained soil.
