Organic Horticulture in the Mid-Atlantic/Rudbeckia triloba

Rudbeckia triloba, the Brown-eyed Susan, is a native wildflower in the Mid-Atlantic, but can also become quite weedy in the garden or field. It is a short-lived perennial, producing flowers in summer and fall. Germination occurs any time during the growing season.

Plants are usually best controlled by pulling. Prevent reseeding by removing spent flowers.

The plant is sometimes cultivated, so consult the garden planner before eradicating. Spent flowers are sometimes left on the plant to attract birds such as the goldfinch or house finch.

Cold-pile composting is safe if flowers or seeds are not present.
