Vertical gardens — think living walls — are of the hottest new garden trends and yet it’s one of the oldest (have you ever grown a vine on a fence or trellis?). A vertical garden is a perfect solution for just about any garden — indoors or out. Vertical garden elements can draw attention to an area or disguise an unattractive view. In a vertical garden, use structures or columnar trees to create vertical gardening rooms or define hidden spaces ready for discovery. Trellises, attached to the ground or to large containers, allow you to grow vines, flowers, and vegetables in a vertical garden using much less space than traditional gardening requires.
