This is a delicate Johnson’s Blue Geranium. The flowers are very small at only about an inch in diameter and it’s petals are iridescent.
This perennial geranium blooms two or three times each year.
I took this photo at the beginning of October when the plant was near the end of it’s last flowering of the year.
It’s a very nice companion plant. I grow it beside heurchera, astilbe and some roses.
