36-48" tall x 12-24" wide. Rudbeckia ‘Prairie Glow’(also known as Brown Eyed Susan) produces masses of blooms from late summer to fall on sturdy, heavily-branched stems that tower at the back of perennial beds and butterfly gardens. Stunning when planted in mass. Plants are bushy but upright, with bright green foliage that provides season-long color. Plants are considered short-lived perennials and are often treated as a self-seeding annual. Naturalize in meadows or borders by leaving seed heads intact, or deadhead to prevent self-sowing. Removing the first flush of blooms will increase flower production over the fall season. Plants are fast growing and require little care. Plant in any well-drained soil in full sun or partial shade. Plants are drought tolerant once established. Deer tend to leave rudbeckia alone in favor of tastier foods.
