The Arnold Arboretum has canceled its annual Lilac Sunday on May 10 - and the picnicking and other events that go along with it.
The Arboretum itself remains open (except for the visitor's center), but visitors are, of course, urged to social distance, which would be hard to do around the lilac bushes on a typical Lilac Sunday.
The Arbs reports that the lilacs will, of course, continue to bloom and that because the paths remain open, you can do some solitary lilac snififng late April through mid to late May. But with a caveat:
We invite you to visit during these weeks of peak lilac bloom, but request that you practice social distancing from one another and respect our plants. If the landscape appears to be too crowded for safe visitation, please return another time.
Also, don't touch anything. You don't know where that bench has been.
