Horticulturist Brie Arthur, author of “The Foodscape Revolution,” will speak at 7 p.m., Thursday, April 19, at the Kingsport Center for Higher Education, located at 300 West Market Street in Downtown Kingsport. A foodscaping visionary, Brie looks at underutilized garden spaces around homes or in the landscaped common areas of planned communities and sees places where food can be grown, inter-planted with non-food ornamental plants for year-round beauty.
