When I read Ashley's post last week (Plant of the Week # 57) his comment about using hedges to create privacy and a sense of enclosure really resonated with me. Why is it that walking through a ferny glade, feeling enclosed by tree ferns, for example, is so satisfying? Or under a spreading oak tree as Michael has described so invitingly? The whole notion of garden rooms and courtyards seems to be based on enclosing the space - creating boundaries. Is it about creating a refuge? Does our brain tell us three walls behind us and only one entrance to guard is safer? Or is it some cultural thing we have got from some of our ancestors? Would some people regard it as claustrophobic to be surrounded by plants? I don't know but I am curious! (By the way - inspirational photos Ashley!)
