Care Tip

Peonies love organically rich soil with good drainage. Plant in full sun, some shade can be tolerated. Prune back Peony stems to the ground level in the fall when they have turned brown. Peonies are a perennial meaning they will die back in the summer-fall months and push up new growth in the spring. Expect shoots to appear late winter-early spring. Blooms March-April. Pick, share and design to your heart's content!
