Waukesha County

The Waukesha County Park System’s Nature Program, housed at the Retzer Nature Center, is recognized statewide for its ecological orientation and experience in applied research on prairie plantings and restoration. Over the history of the Nature Program, we have established prairie nurseries and restoration plantings at Retzer Nature Center and in many of the other parks within the Waukesha County Park System.

Plant Information


 

Native Plant Identification

Need help in identifying a plant found on your property?

Check out Wisconsin Vascular Plant Species or contact Retzer Nature Center

The Ecology staff is available to help with your plant identification. Start by taking a photo or cutting a sample of the plant in question. You can either email the photo or drop off the sample to the front desk of the nature center. Please provide the following information when submitting a plant sample: your name, phone number or email, and information on where the sample was found (sun, shade, wet, dry, and soil conditions). This information will aide in the identification of the plant in question.
