"You don't need to be Spanish, Italian or Greek to enjoy the beauty of Mediterranean gardening. Other parts of the world that also have mild, wet winters and hot, dry summers can take lessons from the many lovely gardens in this Old World region and its centuries, even millennia, of experience with these conditions. These gardens use plants that are able to store the moisture they need in the winter and survive – even thrive – through the summer without irrigation."
"Mediterranean gardening is different from xeriscaping, although they are both waterwise approaches. Xeriscaping is best suited for desert climates with only a few inches of total precipitation for the year. By contrast, Mediterranean gardens require wet winters when plants can store up moisture to see them through the summer. What Mediterranean gardening and xeriscaping have in common is to reduce or eliminate artificial watering once plants are established."
