Do you know anything about a "living fence"?

Question:Of all places, Walmart had this landscaping (Toronto). I am going to try to find out their landscaping source. This has to be the coolest eco-fence. Could be willow but my research hasn't turned up anything satisfactory.

Answers:
Living fences often use the art of espaliering to form a woven shrub line shaped into a two dimensional linear fence. A common design for this technique is the Belgian Fence. Here is a good basic article that describes espaliering.

So the 4x4's and 2x4's are the support structure to train basically an espaliered set of shrubs. All espaliering means is that you train a plant to grow only in two dimensions. There are no real restrictions as to what plants can be used to espalier. Use what grows in your area. Some plants are easier to espalier than other. Shrubs that take hard pruning are best. Trees can be used. Apple trees are quite easy to espalier. Weaving the espaliered plants through a permanent structure like the one you saw at Wal Mart will eventually interfere with the shrubs growth & health. Better to use a structure that could be removed once the shrubs have been trained. Weave the plants with themselves, not the support structure. They do require constant maintenance to keep looking good.
