About Brown-eyed Susan, Rudbeckia Seed
Brown-eyed Susan (Rudbeckia triloba) is a distinctive North American native plant. Branched stems carry an abundance of small yellow flowers with dark centers, and the short-lived plants readily reseed where conditions suit them. It matures at approximately 60 inches tall and flowers from mid to late summer through early to mid fall. Plant it in full sun to partial shade, in dry-medium through medium-wet conditions, with loamy soil or sandy soil.

Tips
Pests & Diseases
Leaf spots and powdery mildew can occur when foliage remains wet or plants are crowded. Provide adequate spacing and airflow, water near the soil surface, and remove heavily affected plant debris. Avoid overhead watering late in the day.
Young plants may be damaged by slugs, snails, aphids, or other chewing and sap-feeding insects. Healthy established plants generally tolerate light feeding. Identify the pest before treatment and use the least disruptive control to protect visiting pollinators.
