I know. We've done this already. Very recently, in fact. But hey, can I help it that suddenly all the flowers are blue lately?
But so anyway. If you know what the flowers are, say something.
UPDATE: Kitty, in comments, suggests that it could be an Anchusa. From looking around on-line, I'm thinking possibly A. azurea?
SECOND UPDATE: Or perhaps Delphinium grandiflorum, says Don. Hard to confirm or reject either of these absolutely, since both Anchusa and Delphinium would fit within the range of photos kicked up by Google and davesgarden.com. The Delphinium looks a little closer in overall size and foliage.
THIRD UPDATE: Okay, okay, geez, it's Delphinium.
