Is black-eyed susan safe for kids and pets?
Black-eyed Susan is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
How do you propagate black-eyed susan?
Division or seed.
