This Saturday, November 12, join Polly Hill Arboretum Executive Director Tim Boland for a guided walk through the grounds. Right now there is much to see, including witch-hazel (Hamamelis virginiana), pictured below, which has begun to bloom. This Martha’s Vineyard native plant has spidery flowers and a soft fragrance. The walk begins at 10 am. This is the first of a winter walk series, which will be held the second Saturday of the month, through March. Tours run about an hour and begin at the Visitor Center. Tours are free, although a donation is always appreciated. For more information, visit www.pollyhillarboretum.org.
