city park, new orleans New Orleans City Park covers a wide area, and is kind of the city's equivalent to London's Hampstead Heath, encompassing some formal laid-out gardens and a lot of semi-wild areas. These beautiful old oaks are festooned with Spanish Moss, which gently floats in the breeze; a typical and unforgettable feature of the American South. For the botanists, Spanish Moss is an epiphyte, related to Air Plants.
