Daft and compact Japanese garden with Shoji Screens perfect for the contemporary home. * I like the moss garden in the courtyard idea.
Planting in between the sidewalk and street. Allium giganteum (Allium 'Globemaster'), steppe sage (Salvia memorosa 'Caradonna'), catmint (Nepeta x faassenii 'Walkers Low') and peat reed grass (Calamagrostis x acutiflora 'Karl Foerster').
A "cluster" / "bunch" of boxwoods makes it more interesting than if placed symmetrical. It's a nice foil.
