This came with our house, and I have no idea what it is! It blooms in the Spring, and is perennial. The flowers are 1/2 inch across, and blue, with purple undertones. The leaves are slightly hairy, and the stems are red. It's growing in part shade, and seems to be happy. It has grown much wider in the last three years, and some of it looks more like a ground cover than anything, but that part isn't blooming. Just the mostly upright part is in bloom.
Sorry for the poor quality of the photos. The wind never seems to stop blowing here! Any suggestions on what it might be?
