Hogweed? #409764

Asked June 25, 2017, 8:53 PM EDT

Sent this question moments ago but bad the wrong email address. Please respond to this request. We bought this cabin in Northern Minnesota. It's yard is full of native plants and wildflowers. However, we found several of these plats that have grown to 2 to 2-1/2 feet quickly. A friend who is quite knowledgeable in plants identified it as hogweed. She sent information from NYS-Department of Environmental Conservation on how to eradicate the weed. We double bagged the flowers and dug out the weeds as recommended. We just want to confirm that this is hogweed and if there is anything else we should do.

Expert Response

I think your plant is  cow parsnip. It is a commonly confused with hogweed but does not grown nearly as large.  It also is toxic and some people are sensitive to the sap.

Your native planting is spectacular.

Thanks, Evelyn, for the response. Should we remove Cows Parsnips if more appear.?  I'd love to maintain the beauty of the native plantings. Yet, we don't live there full time. Can you recommend any resources, books or online publications that I could use to educate myself.

The cow parsnip doesn't have to be removed unless someone in your family is sensitive to its sap.
This information is for Kentucky but the principles apply here.
