Bioswales: Beautiful Landscapes That Work Hard
After several rounds of heavy rains across northern Illinois in the past few weeks, one thing has become abundantly clear: managing stormwater isn't just an environmental concern—it's becoming a necessity. As communities continue to experience more frequent and intense rainfall events, landscapes need to do more than simply look beautiful. They need to work.
That's where bioswales come in.
At our recent Pollinator Day event, Jens Jensen of Jensen Ecology led attendees through the design process of creating functional bioswales. His tour highlighted how thoughtful plant selection and proper grading can transform flood-prone areas into thriving ecosystems that benefit both people and wildlife.

What Is a Bioswale?
A bioswale is a shallow, landscaped channel designed to capture, slow, and filter stormwater runoff. Rather than allowing rainwater to rush into storm drains carrying sediment, fertilizers, and pollutants, a bioswale gives water time to soak naturally into the soil.
Think of it as nature's filtration system.
When designed correctly, bioswales:
Plants are the heart of every successful bioswale.
Native plants have evolved to thrive in the Midwest's changing conditions. Many species develop deep root systems that improve soil structure, increase water infiltration, and stabilize the soil during heavy rain events. These roots create channels that allow water to move deeper into the ground rather than flowing across the surface.
The best bioswale plantings use species that tolerate both periods of standing water and occasional drought. This resilience allows them to perform through Illinois' unpredictable weather patterns.
Some excellent native choices include:

When designed correctly, bioswales:
- Reduce localized flooding
- Filter pollutants before they reach rivers and lakes
- Recharge groundwater
- Reduce erosion
- Provide valuable habitat for pollinators and wildlife
- Add seasonal beauty to the landscape

- Asclepias incarnata (Swamp Milkweed)
- Pycnanthemum virginianum (Common Mountain Mint)
- Panicum virgatum (Switchgrass)
Designing for Success
A successful bioswale begins long before the first plant is installed. Understanding site drainage patterns, soil type, slope, and water flow are all critical components of the design process.
During our Pollinator Day tour, Jens emphasized that every site is unique. The goal isn't simply to plant wetland species in a low spot, but to create a system where grading, soil composition, and plant communities work together to slow, store, and naturally filter stormwater.
When these elements come together, a bioswale becomes an attractive landscape feature that quietly performs an important job every time it rains.
Leading by Example
At Midwest Groundcovers and Natural Garden Natives®, water conservation isn't just something we talk about—it's something we put into practice every day. Across our nursery operations, we've designed our growing facilities to work with the natural movement of water, much like a bioswale functions in the landscape.
Our nurseries utilize a network of retention ponds, swales, drainage channels, and native plantings to capture, filter, and reuse stormwater. These systems collect irrigation runoff, naturally improve water quality, and store more than 83 million gallons of water, allowing us to irrigate millions of plants while reducing our dependence on local aquifers. Drip irrigation, variable-rate pumping systems, and strategically designed windbreaks further improve water efficiency and reduce waste.
The same principles can be applied far beyond the nursery. Bioswales slow stormwater, allow water to infiltrate the soil, reduce erosion, and filter pollutants before they reach streams and rivers. As recent storms across northern Illinois have demonstrated, investing in green infrastructure is no longer simply a sustainable choice—it's an essential strategy for building resilient landscapes and protecting our communities.
By working with nature instead of against it, we can create landscapes that are not only beautiful but also healthier, more resilient, and better prepared for the challenges of tomorrow.
