European style outdoor courtyard works refer to garden designs that incorporate elements and aesthetics inspired by European architectural and landscaping traditions. These can include formal gardens with symmetrical layouts, hedges, and water features, as well as more informal, naturalistic gardens with a mix of plants and open spaces. The styles can range from classic French gardens to English gardens with their rolling hills and diverse plantings. Such designs often emphasize harmony, balance, and the use of color and texture to create visually appealing outdoor spaces.
