Roses are weeds, and violets are too? These little flowers are field pansies, the champion weedy violet. Roses that spread are a messy bunch, with hybrids and cultivars. With them you can hardly tell what you're looking at. Violets are more organized. We can tell that relatively few species invade, and they mostly keep to the weedy places. Field pansies do it with some enthusiasm. Their flowers are only about a half inch long, on stalks that may get twenty inches tall. But if you find some, you will probably find bunches. You might see them in AR, CA, CT, DE, GA, IA, ID, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, MT, NC, NE, NH, NJ, NY, OH, OR, PA, RI, SC, TN, UT, VA, VT, WA, WI, WV, AB, BC, MB, NB, NF, NS, ON, PE, QC, SK, and on GL and SPM.
