Lovelovelove the trellises, and REALLY love the idea of the greenery wall -- a hedge instead of a fence is quite an attractive idea for the vegetable garden (and a secret garden elsewhere) The vegetable and cut flower gardens at Rock Cobble Farm.
Add an arbor to the brick patio. Every indoor room has a doorway, so why not create one for your outdoor room? An arbor or trellis is an inviting entrance to your space, and you can add color with climbing plants such as clematis or climbing roses
This small garden has been divided into different sections, creating the illusion of space. The gravel garden path leads from the patio, to a central water feature, then onto a secluded section at the back, which houses a small summer house.
