A patch of well-tended and mown grass in front of the house became the ornament of American homes after the Civil War—present even in cities, but reaching new dimensions in suburban development. While they might evoke manor houses and their meadows, lawns tend to be smaller, providing a setback from the street that shapes a characteristic American urban geography. Lawns may be landscaped with trees, bushes and ornaments, but are often left connected (in front) as a green plain along the street.

Backyards have been more private recreational and work areas, although they may interconnect in suburban developments. The lawn has also demanded technological responses ranging from lawnmowers—push, powered and riding—to chemicals and irrigation which permit lawns in deserts and seashore areas, although at the expense of environmental degradation.
