DH really hates it, but I love the blue flowers it produces in the spring. After it blooms, I usually pull it up or prune it back. It's back the next year, but I don't mind. It helps with the erosion in my slopey (some will read this as sloppy) garden!
Any day you wake up on the sunny side of the grass is a good day.
