Detention basins are a key part of a successful stormwater management plan. They help capture runoff and filter out pollutants before that water discharges into our waterways. Utilizing native plants in detention basins not only creates wildlife habitat, but the deep roots help excess water percolate and reduce outflow. Water levels in basins can fluctuate considerably in a short period of time. These hydrology changes open the possibility for a diverse range of native plants to grow. This mix prefers species that prefer dry, mesic and wet soils.

The palette of plants can vary from season to season most certainly from site to site. That is why we loaded this mix up with 26 species. Some of the species include native grasses like Big Bluestem and Deer-tongue Grass. Native wildflowers include Purple Coneflower, Swamp Rose Mallow, Swamp Milkweed and Angelica.

This Detention Basin Seed Mix is also good for bioswales. Bioswales are often designed to be like mini detention basins. They are usually adjacent to parking lots and other hardscapes. The hydrology fluctuations in bioswales make this mix a good selection. They are plenty of grasses, rushes and sedges for stability, but also several native wildflowers to make the landscape pop and attract a wide array of insects and birds.

Some things to remember:

Native plant communities can take up to three growing seasons to fully establish. Regreen™ may be utilized as a cover crop while the native plant species are establishing.
