Help with Geums please!

Good morning guys!
I am quite the novice still when it comes to gardening but I learn something new every day. 
I am a massive fan of Geums, they are gorgeous plants.
I have 4 varieties currently; Cosmopolitan, scarlet tempest, mai tai and alabama slammer. 

What I want to know is two things please.

Which varieties of Geum flower the longest? If anyone is able to tell me as many varieties as possible that flower the longest (throughout most or all of spring through to autumn) that would be amazing!
Secondly, is there any way of prolonging the varieties that don't tend to flower all summer so that they will? I know some of the varieties I own don't flower right through and I'm looking for advice on how to get them to flower for as long as possible.

Thank you very much!

    "Mrs Bradshaw" flowers for quite some time, l also have a yellow one called "Banana Custard" which flowers on and off all Summer.
    Have a look at the East of Eden website,  they have a new introduction called "Cumbrian Cherry tart" which is supposed to have a long flowering period.

    My "Totally Tangerine" has never been without flowers. The new ones came out before last year's had even died off and it has spread quite a lot. 
    Pics below show mine as of now and one a poster put on from the RHS Garden.

    Keeping all kinds of them dead headed helps as well (and it gets rid of the problem of the seed head sticking to clothing).
