Introduction

Water pollution is a major problem that affects cities all over the world. Chicago is no exception to this problem, and there are various ways we can address it. One solution is to use plants that are good at filtering water. In this article, we will discuss the different plants in Chicago that can be used for this purpose.

Prairie Cordgrass

Prairie cordgrass is native to the Midwest and is a popular plant for wetland restoration. It can grow up to seven feet tall and has long roots that can penetrate deep into the soil. These roots are efficient at absorbing pollutants from the water. Prairie cordgrass is ideal for areas with standing water or other wetland areas in the Chicago area.

Switchgrass

Switchgrass is a tallgrass native to the Great Plains and is known for its hardiness and ability to grow in many different types of soil. It can also be used to filter water, as its roots are able to take up pollutants and excess nutrients. Switchgrass can be ideal for use in areas with poor drainage, such as along the Chicago River.

Wild Bergamot

Wild bergamot is a flowering plant that is found throughout much of the United States, including the Chicago area. It is commonly used for landscaping and erosion control. It has a deep root system that can help filter water, and it is able to tolerate drought conditions. Wild bergamot can be used in a variety of settings, including gardens, parks, and green roofs.

Gray Dogwood

Gray dogwood is a shrub that is native to the eastern United States and is found throughout the Chicago area. It is commonly used for landscaping and wildlife habitat restoration. Its fibrous root system is good for erosion control, and it is also able to absorb excess nutrients from water. Gray dogwood is ideal for use in riparian areas or along the edges of wetlands and lakes.

Conclusion

Using plants to filter water is a great way to address water pollution in urban areas like Chicago. Prairie cordgrass, switchgrass, wild bergamot, and gray dogwood are just a few of the plants that can be used for this purpose. By integrating these plants into public spaces and encouraging residents to use them in their own landscaping, we can make a big impact on water quality in the city.
