This lovely blue flower came from a packet of mixed seeds a number of years ago. We had no idea if it was an annual or perennial, and since it was in an out of the way place, not likely to be noticed if it were an annual that would self seed, and definitely wanting to perpetuate this one, we transplanted it to a place where we could keep an eye on it. It has reappeared for several years, a much larger and healthier plant than the first year, probably about a foot tall. We still don't recognize it and so I was wondering if anyone out there might know what it is. It has a permanent place in my garden for as long as it wants to stay since it is well behaved and long blooming. I would just like to know who it is. Any ideas?????
