Image:Rain garden.png|thumb|700 px|An image of a typical rain garden, with various vegetation, shrub species, and perennials to increase infiltration, filter out pollutants and reduce runoff/overland flow directed into the facility from rainwater collected from a building's roof. Rain gardens also provide food and shelter for pollinators, bird species, and other wildlife. More complex rain gardens with drainage systems and amended soils are often referred to as [[bioretention]] facilities. <span style="color:red">''A note: The following is an "image map", feel free to explore the image with your cursor and click on highlighted labels that appear to take you to corresponding pages on the Wiki.''</span>

Rain gardens look like typical gardens. However, their [[infiltration]] and [[bioretention]] functions are much greater than normal gardens. By landscaping areas to include a surface depression of approximately 150 mm, rain gardens allow runoff from residential properties to collect and to easily absorb into the ground. Within the rain garden, special types of soil, '[[filter media]]' or [[soil amendments]] increase the amount of water absorbed by the garden and infiltrated into native soils.

Location is very important to a functioning rain garden. When looking at potential locations, look for low areas where runoff can be easily be directed into the garden. Rain gardens are a great option for residential LID retrofits because homeowners can customize the garden to suit their desired styles. They can be planted with a variety of vegetation including [[Shrubs: List| shrubs]], [[Graminoids: List|grasses]] and [[Perennials: List|flowers]].
