A mailing from the Garden Club of East Hampton with pretty painted images of plants native to this area arrived this week and piqued our interest. There, arrayed on a folding card announcing the club’s upcoming annual sale, were milkweed and arrowwood, viburnum, columbine, eastern shadbush, cardinal flower, New England aster, and bearberry — which hungry deer avoid and are in their own ways important parts of the ecosystem, enjoyed by bird and bug alike.
