DESIGNING FOR URBAN HOMEOWNERS; In this design, Plants Enclose an In-Town Lot. Green screens create a private yet welcoming oasis. A limbed-up holly anchors on corner of the front yard, screening power lines yet not making the lawn and garden feel too closed in. Many urban residential environments are cursed with an excess of asphalt, noise, and unsightly views. So for those of us who live in cities, there is much to be said for creating a private oasis, no matter how small the plot.
