Does anyone know what plant this is please?

I thought this plant was a hardy geranium but can't seem to find it in any of my gardening books.  The blue flowers are a very distinctive blue and flower at the top of the stems like delfiniums.  Has anyone any ideas what it is please?

The stem looks like a Delphinium-because it is a Delphinium

It looks like a Delphinium to me, but what ever it is, it looks bloomin marvellous. What a lovely colour. 

Yes it's a beautiful plant - I saw it at a stately home I visited.  Does anyone know which type of Delphinium it is please as having seen it I am desperate to buy one!

I would hazard a guess that it is "Leonora", "Pericles" or "Trudy" (probably the latter), all of which are light blue with white eyes.

Thank you!  I will go hunting for a plant tomorrow
