Of the thousands of flowering plants in the Arboretum, only one, the lilac, is singled out each year for a daylong celebration. On Lilac Sunday, garden enthusiasts from all over New England gather at the Arboretum to picnic, watch Morris dancing, and tour the lilac collection. On the day of the event, which takes place rain or shine, the Arboretum is open as usual from dawn to dusk. Refreshments are available for purchase from 10 AM to 4 PM.
Street parking along the Arboretum perimeter is limited and visitors are advised to take public transportation. Some parking spaces outside the gates will be designated for special-needs visitors. No unauthorized vehicles will be allowed within the gates during the event. A limited number of wheelchairs will be available on a first-come, first-served basis; wheelchairs may not be reserved in advance. Please inquire at the front desk of the Hunnewell Building or at the information tents inside the Forest Hills Gate and Center Street Gate if you or someone in your party requires a wheelchair.
