Terracing is common in Mediterranean gardens — it gives plants and trees good drainage and prevents soil from washing away. It also lets the designer do something different on each level, with a garden on one level and a patio on another, while trees on the upper levels shade those below.
With flowers planted on the upper levels, observers can view them up close without kneeling or walking into the garden. The local wildlife will enjoy this garden as much as the people who see it.
