May
Spring brings flowering trees and shrubs to the F. R. Newman Arboretum; look for redbuds, serviceberries, cherries, crabapples, magnolias, and viburnums; as well as the stunning Japanese primroses along the arboretum’s Treman Woodland Walk. Behind the Nevin Welcome Center, the rhododendrons begin their annual display. Take a spring hike in Fall Creek Gorge and Cascadilla Gorge after they open for the season.
