Few flowers brighten a garden bed quite like the cheerful Rudbeckia, best known as Black-Eyed Susans. With their golden yellow petals surrounding deep chocolate, raised centers, these hardy perennials and annuals are native to North America and bring sunshine to borders, wildflower meadows, and pollinator gardens!
Known for their easy-going nature, long bloom season, and drought-tolerant resilience, they've become a staple in landscapes across USDA zones 3-9. Their rough-textured leaves and strong upright stems make them reliable in heat, sun, and poor soils, while their nectar-rich blooms invite bees, butterflies, and beneficial insects.
Watch the change of the seasons ripple through your landscape by incorporating Rudbeckia in mixed perennial gardens and cozy Cottage borders!
Plant en masse for a brilliant spectacle with these easy-to-grow and maintain perennials! Fill hard-to-mow hillsides and eroding slopes with the spreading Sweet Black-Eyed Susan or Green-Eyed Autumn Sun!
Drought-tolerant and Firewise, Black-Eyed Susans are xeric once established and can handle rocky, sandy, poor soil with ease! Plant in that hell strip along the road and sidewalk where these plants shrug off poor soil and occasional salt spray during the winter months. Use to add sunny blooms to Rock Gardens and mailbox gardens in the full sun all day.
Rudbeckia includes many species beyond the classic Black-Eyed Susan (Rudbeckia hirta), such as Rudbeckia fulgida and Rudbeckia triloba. These plants vary from compact, tidy forms to tall, statuesque meadow fillers, with colors ranging from gold and orange to mahogany-red.

Planting, Care, and Maintenance
Black-Eyed Susans are famously beginner-friendly perennials, growing quickly from seed or nursery plants. Here's how to succeed with them:
- Sunlight: Plant in full sun for the best blooms. Some species tolerate light shade.
- Soil: Adaptable to most soils, but thrives in moderately fertile, well-drained ground.
- Water: Water deeply after planting. Once established, they are drought-tolerant and need only occasional supplemental watering.
- Spacing: Leave 12-24 inches, depending on the variety, allowing airflow to reduce mildew.
- Deadheading: Remove spent flowers to extend blooming, or leave seed heads for birds.
- Cutting Back: In late fall or early spring, trim dead stems to encourage fresh growth.
- Fertilizer: Apply a balanced slow-release fertilizer in spring if the soil is poor.
- Division: Every 3-4 years, divide clumps to rejuvenate growth and prevent overcrowding.
