Vegetative Growth
Spring to early summerPlant develops compound leaves forming mounded clumps 2-3 feet tall and wide. Stems strengthen and foliage becomes vibrant green.
Provide supports or peony rings if needed to prevent sprawling. Remove dead foliage in fall. Apply balanced fertilizer in spring.
Bud Formation
4-6 weeks before bloomLarge buds form at stem tips, often with smaller buds below. Buds gradually enlarge and show white coloration.
Remove side buds for larger blooms, or keep all buds for fuller flowers. Ensure adequate water and fertilizer during this critical period.
Flowering
2-3 weeksLarge white flowers (4-8 inches across) open fully, often with fragrant, ruffled petals. Blooms may be double, semi-double, or single depending on variety.
Deadhead spent blooms to encourage continued flowering. Cut flowers for arrangements early morning when buds just open. Stake if flowers are heavy.
Dormancy
October-MarchAfter bloom and foliage senescence, plant enters complete winter dormancy. Leaves brown and drop; plant appears dead.
Cut back dead foliage in late fall. Do not disturb roots. Peonies require 400-600 chill hours below 45°F to set flowers for next year.

Harvest Tips
Cut flowers in early morning when buds just begin to open. Cut stems at an angle, removing at least 3 leaves on stem for plant health. Recut stems at 45° angle and immediately place in cool water with floral preservative. Buds will continue to open indoors over several days. Leave at least 2 leaves per stem on the plant to support next year's growth.
