Black-Eyed Susan may be
easily confused with:
- Tall Coreopsis
Black-eyed Susan is normally less than three feet tall, while tall coreposis can be as much as eight feet tall. Leaves and stem of black-eyed Susan are hairy; those of tall coreopsis are smooth.
- Thin-Leafed Coneflower
Black-eyed Susan has a much larger flower. Thin-leafed coneflower grows in a cluster. Despite the common names, the disc ("eye") of the brown-eyed Susan (thin-leafed coneflower) is actually the darker of the two.
We started out as wildflowers from the bicycle trails of western Pennsylvania, but we've
grown!
