Johnson County Offices Bioswale
Bioswales are constructed much rain gardens. They are usually long and relatively narrow and are often used for large depressed areas in a landscape like swales between buildings, drainages off parking lots or low areas at the bottom of a hill.
- Bioswales are larger versions of rain gardens
- Great for commercial and large residential landscapes
- Shrubs and trees are often used
This bioswale features a sweep of Heavy Metal Switch Grass accented with wildflowers and shrubs. It was designed for a part sun site by Judy Allmon, Bluestem Landscapes. The gravel mulch zone helps discourage weed growth around the accent plants and doesn't wash as easily as hardwood mulch.
