I am such a push over for a formal walled garden. Fountains, boxwood parterres, marble statues ~ fabulous! Naturally, Hillwood has it all going on. Marjorie Merriweather Post oriented this French-style parterre garden so that she had a bird's-eye view of it from her bedroom window. The perfect sanctuary (I imagine myself hiding out there with a wide-brimmed straw hat and some delicious romance novel). The grounds of the estate also include a Japanese-style rock garden, a rose garden, a putting green, and a "friendship walk" lined with azaleas, wisteria, hydrangea, and English boxwood.
