I'm familiar with Larkspur and it isn't one although the foliage around it does look a little like that .The foliage on the plant itself if you look closely is different. This is the only picture I have of it and I took it a summer ago in a garden on a tour. Thanks for looking. Perhaps some else will recognize it. It was one of the best things in that garden.

Paul, if you got the final ID you are in agreement with, you can close this thread. As Susan said, 'Nestor' is a lighter blue than your image.
If you like, I can move your image to just the Veronica prostrata entry.

I thought it might be Nestor even though the color was a little different because color does vary with different cameras and lighting. If you think it would be more appropriate to list it just as Veronica prostrata it would be ok with me....your choice....thanks.
