Plant a border of upright plants, such as Italian cypress, along the wall. If you’d like to screen the wall completely, plant climbing vines or shrubs that will hide the wall as they grow, such as powderpuff plant, podocarpus, bougainvillea or jasmine. Use lattice, stakes, ties or sometimes cords suspended from the eaves to help support the climbing plants.
Position a hammock or other large piece of yard furniture near the wall. This won’t hide the wall completely, but will draw attention away from it. A few well-placed hanging baskets will help keep your attention off the wall, even when you’re in the hammock. You can also use wall-mounted planters.
Glue or nail birdhouses along the wall at staggered intervals. Add a wall-mounted birdbath to lure more feathered friends.
Use wall-mount brackets to hang sun reflectors at intervals along the wall. You can make your own sun reflectors by tracing patterns on the back of an old CD with a dry-erase marker -- the marker wipes off if you make a mistake -- then cutting through the CD with heavy-duty shears.
Use heavy-duty outdoor glue to attach pieces of broken pots, dishes or tiles to the wall in a decorative mosaic. Lay the mosaic out on the floor first, measure it and outline the placement on the wall. Glue the pieces to the wall, working from the center out.
