These airy structures make attractive additions to gardens and provide a natural setting for alfresco entertaining. Traditional pergolas often include lattice to allow plants to form a canopy.

Modern pergolas come in a variety of materials, and some, such as this structure by Gandia Blasco, forgo plants altogether.

Whatever the style, pergolas should offer shade, either with plants or a retractable awning, available from companies such as Shade FX.
