Brick pavers make a simple, handsome border and work well as edging material too. They're ideal when you want a wide border that keeps grass out of the garden, yet allows flowers and other plants to spill over without intruding onto the grass. You're less likely to chop them up with the lawn mower.
Dry River Bed Landscape Edging. Dark rock gives the illusion of water. Plant grasses and ferns along edge of landscaping. Add dark river rocks to give the illusion of water and follow with larger rocks like you would find along a river bed. Great idea!! Love the natural look of this edging. May be a pretty solution for my drainage problems
