Not sure, but it looks as if the sap isn't filling out the petals for some reason. Have you seen a lot of aphids on the plants lately?

any chance they could have had drift from any weedkillers, yours or a neighbour.

I remember seeing some very strange effects in artjak's garden when the next door farmer had used a weedkiller

Anybody been spraying weedkiller nearby?

Some plants are more sensitive or show the effects in different ways

I think it's in shock 

Moving it from a pot to soil but I maybe wrong what soil have you got also ph maybe a factor. Also it could be the fence it looks new, how strong is the smell of chemicals when the sun is on the fence.

Good point about the new fence, Clueless.

If it is in a pot and has been for a few years then maybe it needs repotting and some fresh compost.  Clematis are hungry plants and need feed.  Tomato feed is the  best to use but they will also deplete the compost in the pot of nutrients and will need repotting.  I have one that has had similiar probs and I spoke with my local clematis nursery (Thorncroft Nursery in Norfolk) and they suggested I repot.  You could send them a pic of your prob and I am sure they would be happy to help.

The best time to repot is Feb time.

It has been very hot this summer and clematis like their thick, fleshy roots deep and cool so maybe they've just been too baked and too thirsty.

Try giving them a really good soak until you're sure the compost is damp all the way through and then give them a feed of liquid tomato food to try and perk them up.  Next spring, feed them with specialist clematis food and make sure they have enough to drink all through the growing season.

I don't know as Ii've never used it but it's worth a try. Just make sure the pots are good and damp first as putiing food enriched water in dry pots can burn the roots and inflict further damage.

I had the same happen to one of mine, with the flowers looking the same and the leaves turning black.I had some aphids on it so I sprayed, fed and watered. The whole plant looks sad now and I'm wondering if I should cut it back a bit. But then maybe new growth would be damaged once it turns cold. Never had this problem before, through years of growing clems.

I think it's been a funny year for clems.  Some of mine are romping away and I have three "Lazarus" clems that have just started to grow after playing dead all year but others are struggling to grow to their usual size and have feeble flowers.

I had surgery to fix both feet earlier in teh year so wasn't able to get out and train the new growth when it started in earnest but I did manage to feed them all and do slug and snail treatments at Easter.

I don't think a long, cold, wet spring did them any favours and then going to heatwave conditiuons and being baked for so long in July may have shocked them a bit.    i suggest trimming out any dead stems, dead heading as much as possible and then hoping for better things next year - along with lashings of proper clematis food in spring.

This year  my Clemetis in a pot started to look realy poorly its one I put in 2 yr ago . I cut it back to soil level and gave it water each day  .It was not long before it sent up thick new growth . But mine could have been Clemetis wilt .

I think you find it is because of irratic watering,How do I know because I have the problem because I have not been able to keep the watering everyday up during this hot weather.They need alot of water and feed when flowering.

My clematis, like yours, has some parts going brown and dying, despite this summer, having loads and loads of flowers. Have made sure the garden was watered on dry days. Could it be ants? Some of petals are curling.

I have another clematis at the front, in full sun, which I put into a bigger pot and it had loads of flowers, but now something has eaten every single leaf! Can't see any insects. This one has smaller pink flowers.
