While nearly all native plants develop deep root systems and can absorb many inches of rainwater in a short amount of time, the moisture-loving species in a Rain Garden are best placed in the central, low part of the area that will receive the most water. All the plants in Prairie Moom Nursey’s rain garden design can be placed in the center, depression area but species like Joe Pye Weed, Common Ironweed, and Prairie Dock with their tall stature are often planted closest to the center. Shorter plants like the Sedges, Ohio Spiderwort and Southern Blue Flag Iris toward the edges will then not get overwhelmed by larger plants.
