Here's the Official Name of the Purple Flowers Popping Up in Ditches Throughout Minnesota

Google and Wikipedia have been great resources for me as I was digging deep about these purple flowers. Based on those resources, the purple flowers popping up in ditches throughout the Land of 10,000 Lakes go by quite a few names, including the following:

dames rocket, damask-violet, dame's-violet, dames-wort, dame's gilliflower, night-scented gilliflower, queen's gilliflower, rogue's gilliflower, summer lilac, sweet rocket, mother-of-the-evening, Good & Plenties (love that one!), and winter gilliflower.

Is Dame's Rocket (The Purple Flowers in the Ditch) An Invasive Plant in Minnesota?

If you believe Reddit and other online forums, you may hear that the purple flowers in the ditches are NOT invasive species.  However, some conflicting information has been provided by the Board of Water and Soil Resources in the state of Minnesota.

Dame's rocket (Hesperis matronalis) is in the mustard family, identified by its four rounded petals and alternate leaves. Dame's rocket is invasive and common in disturbed soils.

Wikipedia and the Wisconsin Department of Natural Resources also shared some info about the expansion of this plant in our neighboring state:  "In Wisconsin, it is classed as restricted, i.e. an invasive species that is already widely established in the state, and causes, or has the potential to cause significant environmental or economic harm."

So, it seems Wisconsin has a bone to pick with these purple powerhouses, too.
