Here is a photo taken on 26th June of a lovely clematis that I have had growing in a pot for several years.




Closeup of one of the flowers below - label long since gone (can anyone identify it?)



But 2 weeks later the next flowers looked like this:



Then I have a newly planted Viticella Venosa Violacea whose buds are opening before the flower has had a chance to form properly - pic below:



 and now a new crop of buds on this are even worse - opening when they are really tiny.  What's going on?

    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?

  • Not a single aphid, waterbutts.

    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?

  • I don't use weed killers and I doubt if my neighbour does, but I'll ask him.  But even if that was the case, would it not have also affected the roses blooming next to the clematis?  They were fine.

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

  • Happy

    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.

  • Thanks everyone for your suggestions.  Just to clarify, the first two photos are of a large flowered clematis, which has been growing in the same pot for about 5 years (tho' I have regularly removed some of the old compost and added new).  It is now growing up the trellis on my new pergola ( which was erected 10 months ago).

    The 3rd photo is of a viticella bought from Taylor's in May, which I have planted in JI compost in a pot which is standing against the opposite side of the pergola.  I have put slow release fertilizer into the pot.

    So neither is in the ground.  As the big one flowered so well in June to begin with, I can't think that the new trellis is to blame.

    LL - I could send a photo to Taylor's - good suggestion.

    So, have any of you any clues as to the name of the large flowered one?  It's a deeper purple than the photo shows.
