This free-form retaining wall posted by Garden Ideas Picture is so beautiful I can hardly stand it! I love how natural the boulders and pebbles look on the hill. And it’s awesome that plants can be mixed into the retaining wall area!
this is my idea of great landscaping. Sculptural shapes of the plants and rocks, gravel. No need to water, prune or clean up leaves/debris. Keep the weed out and run the hose over it once in a while. - My Garden
