Peonies typically bloom once per year in late spring to early summer, with their flowering period lasting about 7 to 10 days per plant

. The overall peony blooming season can extend from April through June, roughly 6 to 8 weeks, if you plant a variety of peony types that bloom at different times

. There are several species and cultivars of peonies that bloom sequentially:

• Woodland peonies bloom first in early spring.
• Tree peonies follow about a week later, often around Mother's Day.
• Herbaceous peonies bloom next, around Memorial Day.
• Intersectional peonies bloom last, extending the season into early summer

By planting early, midseason, and late-blooming peony varieties, gardeners can enjoy continuous blooms for up to six weeks

. Each individual flower cluster, however, lasts only about a week to ten days before fading

. In summary:

• Peonies bloom once annually.
• Individual blooms last 7-10 days.
• Bloom period for all varieties combined can stretch 6-8 weeks.
• Sequential blooming from different species and cultivars extends the overall season.

This makes peonies a cherished spring to early summer perennial with a relatively short but spectacular bloom time that can be extended by careful selection of varieties.
