Soften Imposing HardscapesThe boundaries of small, enclosed spaces can be overpowering, and through the use of plants we can soften and even decorate garden walls in the same way we use wallpaper in our homes. Here, evergreen ivy covers the wall and surrounds the outdoor fireplace, but is kept carefully under control. Create an even more decorative use of ivy by planting different varieties together, allowing them to grow and interweave for a kaleidoscope of colors.
