Just above the Connecticut River in New Hampshire's Coos County, more than a hundred
varieties of herbaceous peonies, tree peonies, and intersectional-hybrid peonies bloom from late May to early July.
Bloom season 2025 has begun despite capricious temperature fluctuations. The garden is open from noon to four daily (except during thunderstorms) beginning June 13.
Visit this website for updates about the progress of the bloom. The week of June 15 marks the bloom of early cultivars. With increasing heat mid-week and a few rain showers, peak bloom has begun.
