If it’s winter it must be time for the winter walk series at the Polly Hill Arboretum in West Tisbury. On Saturday, Jan. 9, the arboretum staff will host a guided walk to look at plants that stand out in the cold season, such as bark and tree structures, along with fruits and berries.

The free tour starts at 10 a.m. and runs for a little over an hour. Meet at the visitor center.
