The Arboretum in May offers a landscape of woody plants from around the world bursting into leaf and flower. View highlights of the season on our interactive map.
Spring is a great time to look for birds in our landscape: view the online gallery of Arboretum birds and other wildlife, download the Bird Checklist, and stop by the Visitor Center to report your sightings. Take a bird walk with Arboretum volunteer and expert birder Bob Mayer, Calling All Birders.
