This is also very well suited to the theme of parterre and orchard. It can include an arbor on which to grow grapes or kiwis or even gourds, with fruit trees espaliered along the enclosing fence. An herb garden can be a wonderful feature in an edible garden. Country gardens can be a theme. The manor house garden is a form of country garden, but I think of country gardens as unpretentious.
Domestic animals can do a lot to maintain a country garden theme.
The edible garden and the cottage garden go perfectly with this theme. Light colored gravel paths, especially straight ones, show up very well in the moonlight, are very easy to navigate. If the garden is designed for moonlight, it will probably also feel unified under sunlight. Many pale flowers are fragrant, so fragrance can be an underlying theme of this type of garden. The wildlife that you hope to attract to your garden form the basis for yet another theme.
