Working on a design for a slice of pie shaped area near a driveway. The owner would like something low maintenance but attractive. The image is attached of my ideas. The purple reddish shrubs are crimson pygmy barberry, The round shrubs are dwarf boxwoods only get 2ft wide by 3ft high about, The focal tree is a true dwarf Hinoki get to about 2/5-3 ft tall, I have some ornamental grasses to soften up the rocks and light post, the rocks are being used to take up some space, add texture and be low maintenance, I then have some impatients as annuals..... What do you guys think? Tips, ideas? It will be mulched with Black mulch. a huge juniper was there previously and we ripped it out....the soil will need some work as it's fairly sandy......Thanks.
