Delphinium

Thanks for your comments and help Leuba :)
I found another reference here, which suggests that the geographic range is correct for your suggestion: https://npgsweb.ars-grin.gov/gringlobal/...

Beautiful flowers Adam. The above reference was the only one I could find. I was sure that it was Delphinium but unsure about species. Hope you can find out a little more about these beauties.
