May is one of the most reliably beautiful months to explore Hoyt Arboretum. Many trees are in flower, our broadleaf and deciduous species are leafed-out, and sunny days are more common.
Spring Blossom Tracker 2026
Follow along with our Spring Blossom Tracker for weekly updates about what’s in bloom and the best places to take in the spring season in the park. Updates will run through the end of this month.
Stop by the Hoyt Arboretum Visitor Center for a trail map and suggestions of where to go and what to see.
