Take part in a beloved Boston tradition! Of the thousands of flowering plants in the Arboretum, only one, the lilac, is singled out each year for a day long celebration. Tours of the lilacs, dance performances, picnicking (allowed on this special day only), and family activities make for a memorable, family day.
