Did you know
- Each golden flower can be 8 cm across with a spectacular burst of stamens — the largest of any Hypericum.
- It thrives in deep shade where few flowering plants survive, making it invaluable as ground cover.
- The plant spreads by underground stolons and can colonize large areas, even under mature trees.
- Despite sharing the name 'Rose of Sharon' with Hibiscus syriacus, the two are completely unrelated.
- Medieval Europeans hung Hypericum over doorways on St. John's Eve (June 23) to ward off evil spirits.
