Tile Mosaic

• Add a mosaic to your garden wall.mosaic image by Stanisa Martinovic from Fotolia.com
  
  Choose a blank, relatively flat wall for installing a tile mosaic. Look to images of mosaics in Barcelona by the artist Antoni Gaudi, Byzantine mosaics or public mosaic art in your area for inspiration. Choose colored stones, pieces of polished stained glass, fragments of tile and even broken china with appealing patterns to compose your mosaic. Effective designs can be large and simple, as the fragmented nature of the tiles provides plenty of visual stimulation.
  
  

Living Wall

• Plant mosses in the cracks of your garden wall.moss on a dry stone wall image by Cliff Lloyd from Fotolia.com
  
  Plantings on a wall bring a surprising vertical design element to the garden. Try a clever wall planting such as a patchwork of multicolored succulents in a wooden frame. Blooming vines twirling around a wire frame create a topiary silhouette. Try a bunny shape draped with ivy for a country touch or cloud shapes planted with blue and white morning glories for whimsy.
  
  

Mural

• Paint a whimsical mural on your garden wall.penguin and lighthouse mural image by rrruss from Fotolia.com
  
  Murals can make quiet garden walls sing. Image sources are endless -- if you are artistic, you can paint anything you dream up, such as a surrealist montage of limbs and melting garden tools; if you feel less confident about your painting skills, try a clean and modern geometric landscape, such as a yellow circle on a blue rectangle above a green stripe. Consider how busy you want your garden to feel; wall murals should not distract from carefully considered and nurtured plantings.
  
  

Fountain

• Install a decorative fountain to add a surprising detail to your garden wall.robinet image by thierry planche from Fotolia.com
  
  Install a fountain on a garden wall to create an old-world feeling. Find cool wall fountains at vintage shops or on travels abroad; unearth reproductions in gardening catalogs or at home supply outlets. Fountains can be expensive to maintain, so be certain you are up to the task -- or leave them disconnected from water sources for a purely sculptural touch.
