Rain gardens are a landscaping design that collects rainwater from streets or driveways and soaks it into the ground. They are constructed in low-lying areas that stay wet after hard rains. Grass, flowers, and other plants are frequently planted in and around the garden to reduce runoff and make the garden look pretty. Helen’s Rain Garden is a park located in Houston, Texas, and it is an excellent example of a rain garden. The Helen’s Rain Garden is very photogenic, and it frequently used weddings and other events.
