Lilac Sunday

Lilacs

May 12, 2024

10:00am–3:00pm

Experience the springtime bloom of our renowned collection of over 400 lilacs. Visit for tours with Arboretum experts, hands-on children’s programming, 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.
