In modern Europe and North America, people often express their political or social views in gardens, intentionally or not. The lawn vs. garden issue is played out in urban planning as the debate over the "land ethic" that is to determine urban land use and whether hyperhygienist bylaws (e.g. weed control) should apply, or whether land should generally be allowed to exist in its natural wild state. In a famous Canadian Charter of Rights case, "Sandra Bell vs. City of Toronto", 1997, the right to cultivate all native species, even most varieties deemed noxious or allergenic, was upheld as part of the right of free expression, at least in Canada.

Garden design is considered to be an art in most cultures, distinguished from gardening, which generally means garden maintenance. In Japan, for instance, Samurai and Zen monks were often required to build decorative gardens or practice related skills like flower arrangement known as ikebana. In 18th century Europe, country estates were refashioned by landscape gardeners into formal gardens or landscaped parklands, such as at Versailles, France or Stowe, England. Today, landscape architects and garden designers continue to produce artistically creative designs for private garden spaces.
