Rudbeckia 'American Gold Rush'
Overview
Uses: Mass plantings, sunny borders, foundation beds, pollinator and native-style gardens, large containers.

USDA Hardiness Zones: 4–9
Sun: Full sun to partial sun
Life Cycle: Hardy Perennial
Growth Habit: Mounding, rounded — dome-shaped and naturally compact

Summary
'Goldsturm' was the standard black-eyed Susan for a generation, and then septoria leaf spot caught up with it. Anyone who has watched a mass planting go black-spotted and ragged by August knows the problem.
'American Gold Rush' was bred to fix it. Brent Horvath of Intrinsic Perennial Gardens selected it from open-pollinated seedlings of Rudbeckia fulgida var. deamii, and the resistance comes from the leaves themselves — narrower and noticeably hairier than the old form, which makes them a poor surface for the fungus. Plants stay clean through wet, humid weather that would leave 'Goldsturm' in ruins.
The habit is the other improvement. It builds a naturally domed mound under two feet, covered from July into September with golden-yellow daisies around dark chocolate cones, with color continuing at a lower level until frost. Massed, it reads as a series of rolling gold hills rather than a flat block.
It swept the industry awards for good reason: an All-America Selections winner, a Pennsylvania Horticultural Society Gold Medal Plant, and the Perennial Plant Association's Plant of the Year in 2023.
Care
American Gold Rush Black-Eyed Susan Care
Full sun gives the densest habit and heaviest bloom; it accepts partial sun with a somewhat looser shape.
Plant in average, well-drained soil. Overly rich ground produces soft, tall growth that can flop, so ordinary garden soil is the better choice. It handles clay, loam, and sand.
Water regularly through the first season. Established plants are notably drought tolerant thanks to a deep root system and need supplemental water only in extended dry spells.
Feeding is rarely necessary. If the soil is thin, one spring application of slow release fertilizer is enough for the year.
Deadheading encourages continued bloom but is not required. The stronger argument is for leaving the final round of seed heads standing through winter — goldfinches work them steadily, and the dark cones hold up well against snow.
Cut back to a few inches in late winter before new growth begins. Divide every four to five years in spring if the clump thins in the center.
Note that this variety is patented, so propagating it by division for anyone other than yourself is not permitted.

Additional Information
What are some common names for this plant?
Two names are in wide use: black-eyed Susan is by far the more common, and orange coneflower is used in native-plant circles for this species group.
How is it different from 'Goldsturm'?
Disease resistance is the headline difference. 'American Gold Rush' has narrower, hairier foliage that resists septoria leaf spot, which has become a serious problem on 'Goldsturm' in gardens and at production nurseries. It is also somewhat more compact, holds a rounder shape, and seeds around far less aggressively.
Is it a true native or a cultivated variety?
A cultivated selection of a native. It was raised from open-pollinated seedlings of Rudbeckia fulgida var. deamii, a straight North American species, so the parentage is native throughout while the plant itself is a named selection rather than the wild form.
Does it spread or reseed the way older black-eyed Susans do?
Much less. Heavy self-seeding is one of the standing complaints about 'Goldsturm', and this variety is markedly better behaved. The clump widens slowly and does not run.
What awards has it won?
It is one of the few perennials to take the full sweep: All-America Selections Herbaceous Perennial Trial winner in 2020, Pennsylvania Horticultural Society Gold Medal Plant in 2021, and Perennial Plant Association Plant of the Year in 2023.
