Orange Coneflower

Flower

Rudbeckia fulgida

Orange coneflower is the perennial coneflower of choice for home gardens - far more long-lived and garden-worthy than the annual or biennial Black-Eyed Susan (R. hirta), which we also carry. It forms dense, spreading clumps of golden-orange daisy flowers with dark brown centers that bloom prolifically from July through September, provides exceptional late-season nectar for native bees, and offers persistent seed heads that goldfinches and other songbirds harvest through winter. The cultivar "Goldsturm" has made it one of the most planted perennials in North America.

Native Range

Origin: Native to the eastern United States.
Native Habitat: Open woodlands, moist meadows, and prairie edges from New Jersey and Pennsylvania south to Georgia and west to Missouri and Kansas.
Current Distribution: Widespread in its native range; extensively cultivated across North America and Europe, particularly the cultivar Goldsturm.

When to Plant

Start Indoors
Start seeds indoors 6-8 weeks before last frost; surface sow as seeds need light to germinate
Transplant
Plant container-grown plants in spring or fall; blooms reliably in the first season from transplant
Direct Sow
Direct sow in early spring after frost; press seeds into the surface without covering
Harvest
No culinary harvest; leave seed heads for overwintering songbirds

Phenology (Natural Timing Cues)

Direct Sow

Direct sow orange coneflower seeds in early spring as soon as soil can be worked, or in late fall before soil freezes for spring germination. Seeds require light to germinate - press into the soil surface without covering. Spring sowings germinate in 7-21 days in warm soil.

Spring: soil temperature above 60°F and last frost within 2 weeks or passed
Soil surface can be raked and firmed for seed contact
Fall: soil temperatures dropping below 45°F, after first light frosts

Transplant

Transplant nursery stock in spring after last frost or in fall 4-6 weeks before hard frost. Spring transplants establish quickly and typically bloom in their first season. Division of established clumps is best done in early spring.

Spring: soil workable and last frost past; soil temp above 50°F
Fall: nighttime temperatures below 55°F, at least 4 weeks before hard frost

Organic Growing Tips

Divide clumps every 3-4 years in early spring to maintain vigor and spread the planting.
Deadhead spent flowers to prolong bloom, or leave them for bird food; goldfinches work seed heads actively through winter.
More drought-tolerant and longer-lived than R. hirta; once established, it requires almost no care.
Powdery mildew can occur in dry summers; improve air circulation by dividing dense clumps and avoid overhead watering.

Common Pests

Powdery Mildew
Aphids; generally quite pest-resistant

Taxonomy

Kingdom: Plantae
Family: Aster family (Asteraceae)
Genus: Rudbeckia
Species: fulgida

Natural History

Rudbeckia fulgida is native to the eastern United States from New Jersey south to Georgia and west to Missouri, growing naturally in open woodlands, meadow edges, and moist prairies. The species has a complex taxonomy with several recognized varieties; the wild type is somewhat variable in flower size and habit. The cultivar "Goldsturm," selected in Germany in 1937 from Czech wild-collected material, became one of the best-selling perennials in North American horticulture following its introduction to the US market in the 1970s and was named Perennial Plant of the Year in 1999. The straight species and its varieties are ecologically superior to the cultivar for supporting specialist native bees and seed-eating birds.

Morphology (Plant Structure & Identification)

Root System
Fibrous and clump-forming; spreads slowly by rhizomes to form dense colonies; divides readily.
Stem
Upright, branching, 2-3 feet tall; rough-hairy; forming dense mounded clumps.
Leaves
Basal leaves large, petiolate, ovate-lanceolate; stem leaves smaller, alternate; rough to the touch.
Flowers
Golden-orange ray petals surrounding a prominent dark brown cone center; daisy-like, 2-3 inches across; bloom July-September.
Fruit
Small, 4-angled achenes in a persistent conical seed head; attractive to goldfinches and other seed-eating birds through winter.

Known Varieties

Common cultivars worth knowing

Goldsturm
The most widely sold perennial in North America for decades; uniform, compact mounds of 2-3 inch flowers on 24-inch plants; extremely reliable and long-lived. Propagated by division only.
Best for: Formal garden beds; mass plantings; consistent performance; cut flowers
Straight Species
Seed-grown plants from wild populations; more genetically variable than Goldsturm with slightly larger and less uniform flowers; superior ecological value for specialist native bees.
Best for: Pollinator gardens; naturalizing; wildlife habitat; meadow edges
Little Goldstar
Compact dwarf selection reaching 18 inches; useful for smaller gardens and front-of-border placement; retains excellent perennial vigor.
Best for: Small gardens; front of borders; containers
