Rudbeckia triloba produces loads of bright yellow 1"-1.5" blooms with black centers on fine, branched, dark stems from midsummer to fall. It may be short-lived but readily self-sows. Also known as Brown-Eyed Susan, Rudbeckia triloba goes well with grasses and other prairie natives. An upright plant that gets fairly tall, it is best planted near the back of the border. It makes a wonderful cut flower.
Rudbeckia triloba is native to a large portion of the United States from Minnesota to Vermont, south to Georgia and westward into portions of the Great Plains.
Rudbeckia triloba prefers full sun and moist, well-drained soil. It is heat and drought tolerant.
