Clematis identification please

Can anyone help me identify this clematis?  It was cut down to 30cm in February, by beginning of June had grown to 3m up wall wires, then flopped, so I corralled it with string to stop it breaking away from the wall. Came into flower about 10 days ago.  I thought it might be a viticella type, all the blooms have 4 sepals.

    Could it be one of the herbaceous clematis?

    It's C. integrifolia. The flowers are lovely but they are hard to position right--not self-supporting, ugly grown up a support, but if grown too near shrubs, they tend to sulk and not flower. So far my best outcomes have been from growing through low shrubs. Yours is doing really well!

    Maybe ‘Blue Boy’?

    This describes it as a viticella x integrifolia, growing up to 2.5m: http://www.roselandhouse.co.uk/clematis/clematis%20blue%20boy.htm

    It also looks like the wild type Clematis viticella, perhaps this is more plausible than C. integrifolia if it has managed to climb 3m?

    I was wondering if it could be C Durandii Especially with the climbing issues. This clematis needs plenty of space in a border to do well. As @Loxley has mentioned a climb to 3m, bell shaped flowers a viticella but is it flowering earlier than normal. Sorry this is where my knowledge ends.

    If it grows to 3m., it can't be C.integrifolia.

    Yes, punkdoc, it would have continued if there had been more wall, but the building being a bungalow, once it got to the roof and the crisscross wires stopped it started to cascade down again, and is now growing back up! It seems to be very vigorous.
    Could well be “Blue Boy” Athelas, the description fits, and it does twine as it gets taller.

    Thanks for all the suggestions.

    Rather nice. After seeing the whole plant - which isn't exactly climbing strongly - I think @GardenerSuze may be right with C. durandii.

    No, not C. Durandii, that has larger flowers which are outward facing..  see below..




    Yours appears to be a hybrid of some sort.. Marran thinks it's 'Blue Pirouette'.. to be confirmed..
