Black-Eyed Susan (Rudbeckia hirta) is a native North American wildflower and a popular perennial plant known for its bright yellow, daisy-like flowers with dark brown or black central cones. Here are some key features and care tips for Black-Eyed Susan:

Flowers: The characteristic feature of Black-Eyed Susan is its striking, golden-yellow petals surrounding a dark brown to black central cone, giving it the appearance of a "black eye." The flowers resemble daisies and are borne on sturdy stems.

Foliage: The foliage is generally dark green and hairy, with a rough texture. The leaves are typically lance-shaped and arranged alternately along the stems.

Height: Black-Eyed Susan plants can vary in height, typically ranging from 1 to 3 feet tall, depending on the variety and growing conditions.

Blooming Period: They bloom from midsummer to early fall, providing a long-lasting display of cheerful flowers that attract pollinators like bees and butterflies.

Sunlight Requirements: Black-Eyed Susans thrive in full sun. They prefer at least 6 hours of direct sunlight daily for optimal flowering.

Soil and Drainage: These plants are adaptable to a variety of soil types but prefer well-draining soil. They can tolerate somewhat poor or sandy soils and are relatively drought-tolerant once established.

Watering: While Black-Eyed Susans are drought-tolerant, they benefit from regular watering, especially during dry spells. Watering should be done at the base of the plant to prevent fungal diseases.

Hardiness: Black-Eyed Susans are hardy in USDA hardiness zones 3 to 9, making them suitable for a wide range of climates.

Maintenance: These plants are generally low-maintenance. Deadheading (removing spent flowers) can encourage prolonged blooming, and cutting back the plants in late fall or early spring helps promote new growth.

Landscape Use: Black-Eyed Susans are versatile and can be used in various landscape settings. They work well in borders, cottage gardens, wildflower meadows, and as cut flowers for arrangements.

Propagation: Black-Eyed Susans can be propagated through division in the spring or fall. Division helps rejuvenate the plants and control their spread.

Wildlife Attraction: The bright flowers attract pollinators, making Black-Eyed Susans a valuable addition to pollinator gardens. Birds may also be attracted to the seeds in the cone-like centers.

Black-Eyed Susans are reliable, hardy, and colorful additions to garden landscapes. With their long-lasting blooms and adaptability, they are popular choices for gardeners looking to add a burst of late-summer color to their outdoor spaces.
