Lilac Sunday at the Arnold Arboretum

Experience the springtime bloom of our renowned collection of over 400 lilacs. Visit for tours with Arboretum experts, hands-on children’s programming, chalk art, and more. Picnicking in the Arboretum landscape is permitted on this day only. Located primarily on the edge of Bussey Hill Road in the heart of the landscape, the lilac collection at the Arnold Arboretum is among the premier collections of these plants in North America. Of the thousands of flowering plants in the Arboretum (many of which can also be enjoyed at this time), only the lilac is singled out each year for a daylong celebration. Pack a picnic and make your way to the lilac collection on Bussey Hill Road. <a href="https://arboretum.harvard.edu/lilac-sunday-2026-map/">Click here to view an event map.</a> Perimeter parking is severely limited and thousands are expected to attend Lilac Sunday.

The lilac collection is about a five-minute walk from the Forest Hills Gate. Parking Street parking along the Arboretum perimeter is extremely limited on Lilac Sunday. No unauthorized vehicles are allowed within the gates. Public transportation is strongly encouraged. Accessibility Parking and Drop-off Parking spaces designated for visitors with disabilities will be available along Arborway at both Arborway Gate and Forest Hills Gate. A handful will also be available at Centre Street Gate and Walter Street Gate. If you are dropping off a visitor with a disability, we recommend doing so at Forest Hills Gate.
