Looks a lot like Edge Ahead, to me, Tee. But, that's just my guess. Has it died back in the winter (dormant)? EA has a stated height of 28 inches with a 5.5 inch flower, so that might be another clue to help narrow it down?

Thanks, Chalyse. It does look like it could be that and the height and bloom size is correct. I will pay more attention to the details.
