English gardens are the best to explore. You always want to know what hides around the corner. I have ladies mantle (the yellow flowering plants), I have sieboldiana hostas, I have the red maple tree, and yellow roses and it looks nothing like the photo above. The brick walls, the crunchy gravel, the urns and concrete ball make this so english and delightful.
Wouldn't it be great to build a maze that had little pockets of gardens in each dead end of the maze? Use some of the fast growing evergreens around the edges to conceal the suprises. I can dream.
