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>

A well-designed rain garden can be maintained with minimal care, which is a great marketing point for persuading homeowners. In the first two years, the plants will need watering to ensure they become established. After this establishment period, the garden should only need simple maintenance, e.g. weeding.

Otherwise, choose taller plants for the back of the garden tapering the height down to the front of the garden. <ref name=LO>Peel Fusion Landscaping

 

Since rain gardens are typically smaller scale homeowner projects smaller stock plants may be considered. Smaller containers may be easier to purchase, transport, and plant, but it may take longer to have a fully vegetated garden. Plant material per Canadian Standards for Nursery Stock, Eighth Edition. Seed planting is not recommended for rain gardens. Plants should be container grown, balled and burlapped or wire basket.

| Often referred to as the floodfringe area. This zone is inundated less frequently (2 – 100 year storm events) and has periodically high levels of moisture in the soil. The ecology of this zone is a transition from the Mineral Meadow Marsh/Beach-type community to an upland community.

| Often referred to as upland area. The ecology of this zone is terrestrial due to its elevation in relation to the filter bed. The zone most closely resembles a Cultural Meadow or a Cultural Thicket community, depending on the mix of grasses, herbaceous material, shrubs and trees utilized.
