Of the thousands of flowering plants in the Arboretum, only one, the lilac, is singled out each year for a daylong celebration.
Tours of the lilacs and other special collections, live music, family activities, food vendors, and picnicking (on this special day only) make for a memorable day. Be a part of this beloved Boston tradition!
The Arboretum is open as usual from dawn to dusk. Refreshments and activities are available from 10:00am to 4:00pm. View the day-of schedule [pdf]. Weather Update: Lloyd Thayer music performance canceled. All other activities to proceed as scheduled.
