Pervious concrete is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge. (Wikipedia)
Native plants have evolved over thousands of years in a particular region and provide a beautiful, hardy, drought-resistant, low-maintenance landscape while benefiting the environment by providing food and shelter.
