Rudabeckia

Rudbeckia fulgida 'Goldblitz' is a compact, low-maintenance perennial (Zones 4-9) that produces abundant golden-yellow flowers with black centers from mid-summer through fall. Growing 24–30 inches tall, it thrives in full sun and well-drained soil, making it ideal for sunny borders, pollinator gardens, and resisting deer. 
Key Care and Growth Tips:
Sunlight: Requires full sun (6+ hours daily) for best blooming and to prevent flopping.
Soil & Water: Prefers average to moist, well-drained soil. While drought-tolerant once established, it prefers not to dry out completely.
Maintenance: Deadhead spent flowers to encourage further blooming. Cut back in late winter or early spring.
Spacing: Plant 18–24 inches apart to form dense,,,tidy clumps.
Hardiness: Highly hardy, heat-tolerant, and handles clay or rocky soil well. 
'Goldblitz' is often favored for its earlier, more prolific bloom compared to similar varieties, offering a reliable, long-lasting display.
