Contrast in color, size, and texture can add interest to your garden. Here I showed you an example of a large area where this was used. Here in a smaller example.
Tucked into a corner of a garden, it would have easy to put in a plant and move on. Instead, a bit more time was spent, turning this corner into a spot that adds to the overall garden.
It also shows what you can do if you only have a small spot. While you may not be able to do everything, you can still do something.
