Most of us are familiar with the idea of using ground covers in the landscape and how they can add a welcome carpet of color.

But, you may be surprised to find that they serve another purpose that is especially appreciated in hot climates.  Ground covers help to reduce the heat from the sun.  They do this by preventing the sun from heating up the ground that they cover.  When the ground heats up, it absorbs heat only to re-radiate it outward.  So, using ground covers is just one way to help cool down the landscape by a degree or two.
