The long low drumlins that roll through this part of the county are stitched together by hedgerows, and in October the hickories in them go the color of old brass. GGC's Hickory Tree & Landscaping Design takes its cues from that landscape, shaping and keeping lawns that sit inside it rather than argue with it — mowing, trimming, edging, and laying out the beds and borders that give a yard its bones. A design here works when it looks like it belongs on the slope it was built into. Season by season the grass is kept even, the lines kept clear, and the whole property kept easy on the eye. Sullivan homes get ground that feels settled and deliberate.
