About This Plant

Sun or partial shade, with well-drained soil. Blooming from late spring to summer, this cheerful, widespread wildflower is considered an annual to a short-lived perennial across its range. Showy golden-yellow ray flowers occur singly atop 1-2 ft. stems, with disk flowers forming a brown central cone. The coarse stems and oval leaves are covered with bristly hairs. Brown-eyed Susan is a food source for Bordered Patch and Gorgone Checkerspot butterflies.

Origins: Eastern U.S., to Central and Southern U.S.
