Living willow walls

I first saw living woven willow fences in "Radical Landscapes" by Jane Amidon.  She highlighted the show garden at Chaumont-sur-Loire 1996 of Judy and David Drew called "Saules dans la Brume" ("Willows in the fog")

The woven willows form a trellis that supports new leaf growth.  "The display thickens as the sun and a microclimate of mist provide nourishment." 

I love the fact that the willows are alive and growing. I love the craftsmanship and artistry in the woven pattern.  I like the fact that it is of a bulky material yet appears light and almost transparent. This is a quality I notice in much Gothic work, like the Oxford University museum.

 
These living fences - or "fedges" - would certainly be suitable as the walls of a green meeting place in the forest.  There are certainly many experts out there who know how to do this:
