Rain Garden

Rain GardenThe native plants in the rain garden develop deep root systems that control erosion, and filter the rain water coming down the slope behind the garden. As the water flows off the street above, it is filtered by our rain garden and the connecting Civic Plaza Wetland Restoration Project before reaching the adjacent waterway.

But the rain garden does more than help keep our Iowa waterways clean!

Each year the bright and cheerful flowers of the rain garden entice beneficial insects to the Enabling Garden. These native plants are left standing over winter to create a haven for pollinators during the cold winter.

Rain Garden Renovations

The rain garden was established in 2006/2007, and now it’s time to renovate in 2016. We will begin by thinning out the tall natives shading out shorter natives. We will also remove non-native weeds that have found their way into the garden during the past decade.

Once the planting has been revitalized, volunteers will install more paths and signs. Visitors will be able to get up close to the vast ecosystem that lives in our rain garden.
