I have always wanted to do this grid type gardening and now it is on my "to do" list. The repetition is graphic and the colors energizing. You could even replace english boxwood for one section of the grids to raise it up and make it even more 3-d. I love this design.
Who said all gardens look alike? Absolutely not. There are some designs that really grab our attention....and yet the repetition of plantings are soothing. Two opposing poles. Opposites attract and are happily married in this garden.
