As self-proclaimed “plantaholics,” Susan and Doug Harding have a hard time sticking to their garden design. Into their 1.2-acre lot in Lincoln, Massachusetts, they have crammed more than 350 rhododendrons, hundreds of plants from The Arnold Arboretum’s plant sales, and dozens of native plants from the Society. They also have a vegetable garden and orchard. Come enjoy the results of their obsessions. This New England Wild Flower Society visit will take place Saturday, June 3 from 10:30 – noon, and is $18 for NEWFS members, $21 for nonmembers. Register online at www.newfs.org, and the address will be provided upon registration.
