Perennials play an important role in accenting many areas of Mount Auburn Cemetery: borders, beds and woodland. Join Frances Doyle and Jim Gorman for a look at some of the perennial stars and understudies to be found there, on Sunday, June 26 beginning at 1 pm. This is a limited walking program. You will car-pool between several area stops.  Fee: $5 members; $10 non-members.  To register, call 617-607-1952, or email Michelle Pizzillo at MPizzillo@mountauburn.org.
