This one jumped up in today's random selection. Johnny commonly escapes to live free among our other plants. In this case they've spread to weedy places around a country church, and densely in a fallow field across the road. I've seen them from Florida to Michigan, so it's hard not to count them as a wild flower. There are wide variations in color, but in my experience they have looked much like these. Johnny has been reported from every state except AZ, CO, HI, ID, MT, ND, NM, NV, SD, TN, WV, and from AB, BC, MB, NB, NF, NS, ON, PE, QC, and SK.
