The last time I was about to mow the grass, my son ran out to me and begged me to spare the life of this weed. He said he wanted to let it grow so that he could see what kind of flower it would make. I played along and mowed around it, and this purple flower was our reward.
It grew a little over a foot tall–maybe 18 inches–and I have noticed our neighbors eyeing it from their side of the fence, wondering if we planned on letting the seeds blow around.
We actually cut it and brought it inside as a table centerpiece!
