Lilac Sunday

Of the thousands of flowering plants in the Arboretum, only one, the lilac, is singled out each year for a daylong celebration. Mainly located on the edge of Bussey Hill Road in the heart of the landscape, the lilac collection at the Arnold Arboretum of Harvard University is among the premier collections of these plants in North America. Lilac Sunday has been celebrated at the Arnold Arboretum since 1908.

Tours of the lilacs and family activities are available from 10 a.m. - 3 p.m., but the Arboretum is open as usual from dawn to dusk.  Learn more about picnicking rules, tours, parking options, and accessibility on the Arboretum's event website.
