4 Things Every Peony Fan Needs to Know
Peonies make wonderful, long-lasting cut flowers that generally persist for over a week. You can pick them as open as you like, but for the best vase life, harvest them while in bud.

If the buds are still hard, then I leave them to ripen longer, but if they feel soft—similar to a marshmallow—I pick them.
