Dormancy/Planting
Fall through early springBare roots or potted divisions are planted in fall (September-October) or early spring. The plant is completely underground.
Plant with eyes just below soil surface; deeper planting delays flowering. Mulch after planting. Fall planting allows root establishment over winter.
Spring Emergence
4-6 weeksRed shoots emerge from the ground as temperatures warm. Foliage unfolds into compound, finely-textured green leaves.
Remove any winter mulch gradually. Watch for late frost damage. Support emerging shoots if necessary.
Vegetative Growth
4-8 weeksPlant grows vigorously with lush, dissected foliage on sturdy stems. Leafy growth continues without flowering in younger plants.
Water regularly. Apply balanced fertilizer in early spring and again after blooming. Add support cages around stems early to prevent splitting.
Budding & Flowering
2-4 weeksFat buds form at stem tips in late spring; large, double white flowers with creamy yellow centers open in succession over 2-3 weeks. Flowers are highly fragrant.
Stake plants with support rings or cages to prevent stems from splitting under heavy flower weight. Deadhead spent flowers to extend bloom if desired, but leave foliage.
Post-Bloom & Dormancy
6-8 monthsFlowers fade and drop. Foliage remains green and photosynthesizes through summer and into fall. Leaves gradually turn reddish before dying back after frost.
Do not cut back foliage until after hard frost. Reduce watering. Apply low-nitrogen fertilizer after blooming. Leave stems intact for winter interest.

Harvest Tips
Cut flowers in early morning when buds are just beginning to open and feel slightly soft. Cut stems at a 45-degree angle and place immediately in cool water. Buds will continue opening indoors over several days. Leave at least two sets of leaves on the plant when cutting to support future growth. Avoid cutting more than one-third of the plant.
Fun Facts
- 🌱 Duchesse de Nemours was introduced in 1856 and remains one of the most popular peony cultivars worldwide—it has scarcely changed in appearance for over 160 years.
- 🌱 Peonies are notoriously long-lived; a single established plant can bloom reliably for 50-100+ years with minimal maintenance, making them true heirloom perennials.
- 🌱 The common sight of ants crawling on peony buds is harmless; ants feed on the plant's nectar secretions but do not prevent flowering—a persistent gardening myth claims otherwise.
