In keeping with CDC and Harvard COVID-19 guidelines for large gatherings, The Arnold Arboretum of Harvard University is canceling Lilac Sunday 2020. All formal activities such as tours, family crafts and science, and performances scheduled for Sunday, May 10 are canceled. Picnics will not be allowed on this or any day.
The lilacs will bloom as usual over the course of several weeks (typically late April through mid-to-late May). 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.
