Black-Eyed Susan (Rudbeckia hirta) is a beloved native North American wildflower producing vibrant golden-yellow daisy-like blooms with a distinctive dark brown center from midsummer through fall. Hardy in zones 3–9, it grows 2–3 feet tall and thrives in poor, dry soils where other flowers struggle — making it ideal for naturalistic plantings, pollinator gardens, and tough, unirrigated spots. Black-Eyed Susans are exceptional wildlife plants: they attract monarch butterflies, native bees, and goldfinches (who eat the seed heads in winter). Short-lived perennials or biennials, they self-seed prolifically to maintain their presence year after year with zero maintenance.
Direct sow Black-Eyed Susan in fall (for spring germination) or in early spring with stratification — seeds need cold-moist treatment or natural freezing to break dormancy. Or start indoors 6–8 weeks before last frost. Plant in full sun to light shade in any well-drained soil — Black-Eyed Susans actually perform better in lean, dry soil than in rich, amended beds. Space 18 inches apart. Water during establishment only; mature plants are drought-tolerant. Deadhead spent blooms to extend flowering and prevent excessive self-seeding, or leave seed heads for birds. Divide clumps every 2–3 years in spring to maintain vigor. Virtually pest and disease-free — one of the most low-maintenance perennial wildflowers available.
