Definitely a clematis 

[mdjlucan]

thanks It's just the name I wanted to know what one it is

[mumofstig]

It could be this one  https://www.sarahraven.com/clematis_viticella_royal_velours.htm

but colours vary from screen to screen, so can't be sure

[Aunt Sally]

Could be Jackmanii.

Could be Jackmanii.    I am currently going through my clematis catalogues of which I have two.    Please could you tell me the colour under the petals, and when did you prune it ?    Mrs Bouquet

[mrs bouquet]

Yes, definitely agree with Jachmanii Superba.     Flowering months June to September.   H. 15/20ft.  Any aspect.    This variety will bloom on new wood.     Stems should be cut back to two healthy buds late Feb early March, removing previous growth, this is normally about 9 to 18" from the ground. If left unpruned it will still flower well, but will become leggy and bare at the base.     These are generally my pruning guides, and do not be tempted to do it earlier and watch for frosts.     Good Luck,   Mrs Bouquet.  PS watch out for slugs as well on the tender shoots !

[Aunt Sally]

Thank you Mrs B.  I feel proud you have agreed with me 

[mumofstig]

Just a thought  - if it is flowering now, we would all be wrong 

[Aunt Sally]

It’s season is early/mid/late summer and it has been a remarkably hot spring.  Lots of flowers are early this year.
