April showers bring May flowers, but they can also bring stormwater runoff. With a little effort and planning, though, those flowers can help to stem runoff when planted in a rain garden. It is estimated that a rain garden can absorb 30 percent more water than a conventional lawn of the same size. Rain gardens help to soak up the water, filtering and removing some of the excess fertilizers before they reach the Bay. By reducing the total amount of water that enters storm drains, rain gardens also help to prevent flooding and shoreline erosion. Here is a list of rain garden plants. Can you match them with their descriptions?
