2014 Peony Season Comes to a Close

Current Status as of June 24: A few stray blooms but this year's season has pretty much ended. Thanks to everyone---members, visitors, student interns, volunteers, staff---for making this one of the best peony seasons ever.

What is peak bloom? Peak bloom represents an ideal time to visit the garden and see many different peonies in bloom. Bloom season estimate in any given year is a staff "best guess" and will be updated as spring progresses. Difficult to predict exactly when the peonies will bloom. They choose their own schedule!



The Peony Garden peak bloom time usually begins in late May to early June. This is when a majority of the herbaceous peonies burst into an intense display that usually lasts about two weeks.

  • Peak bloom may arrive more than 10 days early if unusually warm weather "pushes" the garden, or it can be delayed if we have a week of cool days and nights. The duration of peak bloom depends on the weather, too. Hot dry winds take the garden down days too early for us; calm cool days can extend the peak season by nearly a week.
  • The Peony Garden is always into its post-bloom summer growing season by the Summer Solstice.


An urban myth says there is a peak day when all are in bloom. Not so - there is a peak season. Since each peony blooms on its individual schedule based on weather and genetic programming, there has never been a "peak day" when all are in bloom. Nor will that ever happen. So enjoy them in bloom and revel that Nature runs on its own calendar.
