Black-Eyed Susan (Rudbeckia hirta) is a hardy wildflower recognized for its cheerful, daisy-like blooms featuring bright golden-yellow petals that radiate around a distinctive dark brown to nearly black central cone. Sometimes called gloriosa daisy or yellow ox-eye daisy, it is native to North America and thrives in prairies, meadows, and open fields, where it often grows in colorful swathes. Its coarse, hairy stems and leaves give it a rugged texture that contrasts with the smooth brilliance of its flowers.

Blooming through summer into early autumn, it serves as a nectar source for bees, butterflies, and other pollinators while producing seeds that feed birds. Culturally, it is celebrated as a symbol of encouragement and resilience, often used in naturalized plantings and wildflower mixes. Its ability to adapt to a variety of soils and climates has made the Black-Eyed Susan a beloved emblem of North American landscapes, combining ornamental charm with ecological importance.
