How to Grow

The ideal foundation for establishing Rudbeckia ‘American Gold Rush’ involves planting location selection and proper soil preparation. Ensure the chosen spot receives full sun exposure throughout the day, as insufficient light leads to weaker stems and reduced flowering. Plant in average, evenly moist, well-drained soils; while it tolerates dry spells, consistent moisture during establishment helps it maximize size and vigor.

Ongoing cultural care for this Black-eyed Susan is generally minimal due to its low maintenance classification. It handles hot and humid summers well and develops drought tolerance once its root system is mature. Avoid overly rich or fertile soils, as these conditions can lead to flopping, which may necessitate staking for support.

To maximize flower production, deadhead spent blooms consistently throughout the season. This simple task signals the plant to redirect energy into creating new flower buds rather than setting seed. Plan to divide the clumps every four to five years to maintain robust growth habits and prevent overcrowding in the perennial bed.

Beyond the garden bed, this specific Black-eyed Susan is suitable for use in large containers, offering season-long performance where seasonal turnover is desired. Furthermore, gardeners should utilize its exceptional fresh-cut flowers; the showy blooms with their dark centers are classic elements for fresh arrangements.

Consider pairing Rudbeckia ‘American Gold Rush’ with plants that share similar full-sun requirements and dry-to-medium moisture needs, such as ornamental grasses, Coneflowers (Echinacea), or Russian Sage (Perovskia). This cultural compatibility ensures that all components of the scene thrive together without specialized care.
