Certainly not Scabiosa caucasica which is the normal one. It could be one called S. graminifolia but I have not got a really clear picture of that one. It is too tall for S, columbiara and that one has darker leaves. I wonder if it is perhaps a Jasione? They are members of the Scabious family, but the only one I know is a tiny British native, but there are cultovated ones.
