Stone walls run along the dooryards of Danbury like old seams, and the roads bend where the Still River valley bends — brick and hat-shop grit down at the bottom, hardwood ridges lifting on either side. Supreme Green Landscaping works those yards: mowing, trimming and edging, aeration and weed control, shrub and flower beds coaxed back into shape, and the things that stay put underfoot — patios, walkways, retaining walls, outdoor fireplaces, water features and low lights set into a planted bed. There is a plain pleasure in a mown line held true to a fieldstone wall, in a fall cleanup that lifts the last oak leaf off the grass before the ground goes hard, in a stump ground flat where a limb-heavy maple used to lean over the drive. Deep in winter the plow opens driveways in Danbury, Bethel, Brookfield, Ridgefield, Newtown and New Fairfield before the first headlights need them, and the lots in Wilton, Redding, New Milford, Sandy Hook, Westport, Darien, Easton and New Canaan come up black and clear. Then the light lengthens, and the same yards are standing ready to go green.
