Two diverse Lexington properties offer a wonderful contrast in garden content and gardening styles. Jim Jones, past president of the Rock Garden Society, began gardening with something of a â€œone of eachâ€ mindset. â€œReality set in after a while, but not before I had accumulated quite a collection of oddball plants.â€ Recently, his focus has shifted to a week-by-week distribution of bloom across the seasons, with the fall portion dominated by native species. Carolyn Plourdeâ€™s garden was designed as a place of beauty for herself and her family with hardscape, a waterfall area, and large plantings. Over time, it has been reworked and expanded in many ways. Learn about â€œgutterâ€ gardening between sidewalk and road, and how a flock of chickens can add delight to the garden and eggs to your basket. This tour, to be held Friday, September 17 between 10 am and 1 pm, is sponsored by the New England Wild Flower Society, and costs $32 if you are a NEWFS member and $38 if you are not.
