Hello,

No that is not a different species of rhubarb and no it is not edible. The variegated plant in your picture is Goutweed or Bishop’s weed (Aegopodium podagraria). Read more here: https://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=243464&isprofile=0&

It is in invasive species in Michigan. Read more here: https://www.misin.msu.edu/facts/detail/?project=misin&id=54&common=Bishop%27s+goutweed

Because of its rhizome root system, it can be difficult to eradicate it. As you have just a few plants, it may not be difficult to pull up the plants and dispose of them. If it expands to a large area, smothering may be the way to remove it. Mow it down as low as possible; cover the area with cardboard, kraft paper or several layers of newsprint; cover the paper with 3 inches on mulch to suppress the growth. Pull out any stray plants that escape the cover. It may take two or three seasons to successfully eliminate the plants.

Thank you for contacting Ask Extension.
