Woodland peonies produce seedpods that are as gorgeous in this season as the flowers are in April.
These are all from my Paeonia obvata var. alba.
My Paeonia japonica produces similar seedpods but a bit smaller. These photos were taken about a week ago and the seedpods are even more open and exotic-looking now.
Though this plant is from the late Seneca Hill Perennials you can find similar plants at Song Sparrow, Hillside Nursery, and Plant Delights — just not every year. It may take a bit of searching but they are worth the effort.
If you'd like to see them in bloom, click on peonies in the category list.
It's also worth noting that the leaves on woodland peonies do not have the fungal problems that my regular garden peonies seem to suffer from by late summer. All my woodland peonies are still fully leafed-out and looking good.
