I have found the above in a nearby garden of a friends property. Is this japanese knotweed ? please remove spaces after www and copy into browser to view. (Cannot post links being a newbie)

pimento

I'd say so.

No, it doesn't look quite right for Japanese knotweed.

I think it's a close relative, the Russian vine, Fallopia baldschuanica, or something similar, like Silver Lace Vine. You can Google these yourself & compare.

I think the leaves are slightly the wrong shape. Japanese knotweed the leaves are a bit rounder and smoother than the picture you've posted, OP. MOre like the ones pimento posted.

No doubt there are different varieties but I've been looking at plenty of it today in a nature reserve and whilst it's similar, what you've posted doesn't look the same as what I've been looking at. davesnave's picture does look a closer match to yours.

roses

Japanese knotweed is more red than that

Thank you for the replies do you know whether russian vine can cause the same structure damage as knotweed or effect mortgages like the latter ???.....

thank you in advance

Hi, I've been battling the dreaded Japanese Knotweeds for nearly two years and yours doesn't look like it. it has stems like bamboo and grows upright out of the soil. mine was like a tall tree from afar but close up it was hundreds of bamboo like stems. Have a look at this link -

Doesn't look like Russian Vine to me - that looks more like a white wisteria. Mind you, it doesn't look like the Japanese Knotweed I've seen either.

Poor you, you have my sympathy

definitely not knotweed.

I had a similar battle with knot weed and did eventually win, spray repeatedly with glycophosphate as soon as any of it sticks its head above ground, injecting into the stems of any really persistant growth, including the neighbours side if appropriate. Once it seems to have been killed or only a few straglers are still reappearing , then use a systemic broad spectrum weedkiller on the ground reapplying after 3 months(you won't be able to use the ground for upto six months from the last application).
It took me nearly 3 years but I did eventually win.
