The Friends of the Hopkinton Seniors will hold their annual Summer Vegetable and Flower Fundraiser on Saturday, May 18, from 9 a.m.-1 p.m. at the Hopkinton Senior Center. Summertime favorites such as heirloom tomatoes and vegetables, essential pollinator flowers, herbs and container varieties from the center’s greenhouse will be available along with a variety of garden accessories and perennials at wallet-friendly prices. Donations from community members — recently divided perennials, overplanted vegetables, herbs or flowers from a home garden — can be dropped off May 16 and 17 at the Senior Center front desk.
