Our Countdown for Spring 2013

This bloom season estimate 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!

Current Status as of June 21: The bloom season is over. Several late-blooming peonies have their final flowers, but the Peony Garden is not a floral destination.

What is peak bloom? Peak bloom represents an ideal time to visit the garden and see many different peonies in bloom. 



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.
