Frequently Asked Questions
01 Do black-eyed Susans come back every year?
Yes — Rudbeckia fulgida 'Goldsturm' is a reliable perennial in zones 3–9. Some annual black-eyed Susans (R. hirta) reseed but don't overwinter. Check the species on your tag to know which you have.
02 Do black-eyed Susans spread?
They spread gracefully by short rhizomes and self-seeding, but never aggressively. A single plant expands into a 2–3 foot clump over several years. Deadhead the seed heads if you want to prevent volunteers.
03 Why are my black-eyed Susan leaves spotted and yellowing?
Usually septoria leaf spot — a fungal disease that appears in humid summers. Water at soil level (not overhead), remove infected leaves, and space plants for airflow. 'Goldsturm' is particularly susceptible; newer cultivars like 'American Gold Rush' resist it.
