Lots of people are asking, “What is this? Is it a weed or flower?”
Well, an old time gardener would say, “A weed is a flower without an advertising agency.”
So, what is it?
Although used and spread by colonial settlers, it’s edible for people but it is not eaten by local wildlife or insects. Roots are used like horseradish and seeds spice up food.
Yet in the natural landscape, it has become an invasive weed. It competes with native vegetation and it can establish in a relatively stable forest understory. It can grow in dense shade or sunny sites. Garlic mustard is also allelopathic, producing chemicals that inhibit the growth of other nearby plants and mychorrizal fungi needed for healthy tree growth and tree seedling survival.
