Japanese knotweed or not?

Hello, I'm looking for a little help! 

We have been told that we have Japanese Knotweed in our garden and are due to sell the property. I have attached a photo of the plant / weed in question. 

Could someone confirm that is is Japanese Knotweed (I have Googled the plant and the flowers are not the same)...?

If it isn't Knotweed, do we know what it is?

Thanks in advance!

James

    Is it possible you can take another photo further out and one closer around the lower section.

    Could be totally wrong but it looks like you have Japanese Knotweed along the lower section with another plant with Myrtle type flower growing around it. In other words 2 plants in that scramble. Let’s see what others think.

    Hi James. It does not look like JK to me. Have you by any chance a picture of the flowers? If not could you take a picture of the stems showing more detail.

    Hi, thank you for your quick responses. I'm not at home at the moment but I have managed to zoom in on some of the details...

    Does this help?

    This does not look like JKW, I have/had it & this does not look like mine.

    The fluffy white flowers and the smaller leaves look like old man's beard (a native form of clematis).
    The larger leaves look to me like suckers from a shrub  (maybe lilac? is there a shrub nearby?). The stems don't look fleshy enough for japanese knotweed.

    Thanks for re-posting those photos. The reason I asked for a picture further out, it looks like there is Clematis Terniflora climbing up the boundary. I can see two types of leaves.

    The Clematis can be quite invasive and sucker from a plant planted quite far away. The other plant along the bottom still looks like Japanese Knotweed to me at the moment.

    I agree with JennyJ about the Clematis but I'm still not seeing JK there. When you get home can you take a close up picture of the stems with the larger leaves.

    I agree about the clematis too.  But I do think the other plant could well be JKW, perhaps looking a bit less robust than usual - could be regrowth after some next door has been sprayed, perhaps?

    I have to agree with borderline.

    I think you may have two plants, one of which may be JKW, but it's really difficult to tell. Can you trace the stems down to check ?

    The alternate leaf arrangement, leaf venation and leaf shape all look to suggest that some of those leaves on some of those steams may be JKW.

    The other plant looks to have opposite leaf arrangement for instance.

    Everyone, thank you for your help. 

    I have managed to get back to the property this morning to take some further photos. As many of you suspected there are two different types of plant / weed growing here. There is a small amount of what I suspect is JK. Further pictures attached.
