I think these peony seeds are really very beautiful. Glossy red-brown, to glossy black, and presented neatly, in their little packets, if undisturbed they will stay on the plant through the winter adding some interest to an otherwise dull garden scene.
@skipt07 Not quite grape sized. The whole seed pod in the picture is probably two to two and a half inches across and the individual seeds (the bigger ones) about half an inch long. The size of the pods and the number of seeds each one produces varies pretty widely.
