Can you tell me what clematis this is?

This was bought as a present- the person who gave it to us lost the wrapper. Any ideas - and what group it's in? Planted it in June

If its blooming now then it's probably a group 3.

It is hard to id them from flowers because the colours vary on the photos. My Rouge cardinal looks like your clematis but if you Google the name it can look dark red, burgundy or a purplish red. I think it depends on the soil and light it has plus the photos can vary according to saturation. It's anyones guess.

Hard to tell, there are so many. It could be Niobe, flowers June - September.

I'd agree with @Busy-Lizzie - it looks like Niobe. Group 3  - cut back hard in spring.
You'll need to ensure it has plenty of water as it's very near that fence.
The flowers on clematis  change considerably in colour, depending on their maturity and how much sun they get

It also has quite strong ribbing on the flowers, so if it has those, it could be that.
However - there are lots of clematis that can look quite similar, and it could well be a later flowering variety if it's only just flowering now. My Niobe starts at the very end of May /early June.

It does look like it could be Niobe but, whatever it is, I would be making sure it's getting plenty to drink all thru summer and a very good feed next spring.  I would also swap those pebbles out so it could have a thick mulch of well-rotted manure for winter, once the autumn rains have soaked the soil.

Given enough feed and water in its early years  it will establish strong roots and grow more stems each spring and these will need training to stop it getting into a tangle.  If it is Niobe it is a group 2 - http://clematisontheweb.org/new-clemdetail.cfm?dbkey=27 - and will not need a heavy prune next spring but will need dead-heading and possible tidying up after the first flush of flowers is over and then a good feed again to encourage the second flush later on.

It can also be treated as a group 3 and hard pruned in spring and it will then just have one steady flowering period from June or July onwards.

It looks like my Mrs. Nelly Thompson, it's unclear from the image if the section of the petal has a 'dark maroon rib toward the end-point of the petal'. If it has, it is Mrs. Nelly Thompson clematis - indeed a lovely plant, Taylors sell this type cultivar ... - https://taylorsclematis.co.uk/clematis-mrs-n.thompson.html

Mrs N Thompson is not as subtle as the OP's pic - http://clematisontheweb.org/new-clemdetail.cfm?dbkey=333 

Look at the second photo on here - http://clematisontheweb.org/new-clemdetail.cfm?dbkey=27

I had a niobe once in UK and it was a lot redder but colours are so variable re photos etc.

My pic shows how different the flower colour can be too @Bijdezee - they get quite pinky as they fade, and more so if in a sunnier spot. They're quite a deep red/purple when opening.
If the flower in the OP's pic isn't very big, it won't be Niobe either, as the flowers are quite big on it, as opposed to the viticellas for example.

Could be youth too tho.  I have a young, recently planted Astra Nova which has flowered for the first time and they're barely 5cm wide whereas at maturity they are 6 to 8cm wide.
