The 80 degree yesterday was perfect, and one task was weeding the mystery plant that was rapidly popping up in two large spots in my flower garden. I had a sneaking suspicion it was something I had planted, but a casual chat with a neighbor got me thinking it was a weed that I did not want to get too established. I had nearly decimated one patch when I saw that the plant was emanating from dried stems and a tell-tale clump of potting soil. This was a perennial I had planted last year! It was nowhere on any of my diagrams, and there was no tag lying around, but when I turned to my photos I sadly realized it was Ageratum (mist flower), a plant that did really well last summer/fall and has lovely blue flowers. I think it will bounce back, but lesson learned and vindication--see, Mr. Do, my "crazy" metal plant tags serve a purpose!
