A wildflower native to the United States, black-eyed Susan is a biennial or short-lived perennial that features daisy-like yellow flowers blooming from May through October with dark chocolate brown discs atop stiff stems and hairy leaves; the word hirta means hairy. Related cultivars are commonly called gloriosa daisies—they are larger-flowered and come in shades of red, yellow, bronze, orange, and bi-colors. Plant in full sun, they withstand heat and self-seed. Bouquets are presented to the winner of the Preakness Horse Race in Baltimore, Maryland.
