Mystery Solved…Mostly

During the winter a plant with large leaves sprouted in the garden.  I had no idea what it was, as I had planted a variety of annuals there to provide blooms for hummingbirds and butterflies and I wasn’t sure if it was one of them. The plant froze back twice during the winter and I never thought I would find out what it was. Finally, it revealed itself as an Ageratum.

I had originally planted these sweet little Ageratum that are tumbling down the rocks and now this really big one has appeared.  So I am asking the experts out there to explain this.  I think it is a throwback to its original form, before being miniaturized. I do have a Wild Ageratum (Mistflower) in the yard, but this is not the same.
