The same basic techniques for creating nests in a room space can be used in a walkway. This pathway does it all. A beautiful vista is created by the archway and the opening at its end, drawing visitors to explore the tunnel. If that tunnel were closed at the end, it would seem spooky instead of exhilarating and inviting. A vista is a must! Another must: the encompassing plantings over the arch. Without the addition of grapevines, climbing roses or other climbing plants, an archway can can seem too empty.
