Does it flower? Spotted a very similar plant growing out of the wall near the mother-in-laws except it,had large white flowers. Could it be a honeysuckle?
It does flower but they are not large flowers. https://www.google.com/search?q=jap...-gb&client=safari#vhid=fQKLC1hZuLgX6M&vssid=l
you might think it’s controllable , but it isn’t . If you’ve got any near your house, dig it up! A spade may not do the job, but a jigger pick will. bamboo is already on the radar of mortgage lenders-everyone thought Japanese knotweed was the muts nuts in the 1800s
That sounds more like bindweed. I have it over the fence at the bottom of my garden and it grows like the clappers.
I've got some near(ish) my house and other places in my garden. Been there ages. When it spreads too much it gets the chop. It's easily controllable and nowhere near as scary as Japanese Knotweed.
Difference between the two surveyor told me is that Knotweed is capable of penetrating concrete, bamboo could only do the same if there were existing cracks or gaps.
It wasn't planted intentionally along railway embankments. It was Introduced into Britain in the mid 19th century by the botanist Philip von Siebold as an ornamental plant. His American botanist friend took some to the US where it has become just as much a pest as it is here. One of the problems is that here it is a single sex plant and propogates via its rhizomes. It is also a notifiable plant under the Environmental Protection Act along with Giant Hogweed and Himalayan Balsam.It is not quite indestructable but exceptionally difficult to eradicate. Chemical treatment with Glyphosate can take years and 'dig & dump' is effective but requies arisings to be buried with 9 metres cover. As for Oakwell there was an infestation to the north of the training pitches some years ago.
I'm not saying they introduced it, however It was 100% also planted by whoever was running the rail network at the time, lets call them Network rail for the sake of it. I did quite a lot of research into it and at length discussions with the surveyor. Also from my home insurance background approving surveys etc. Network rail have also had legal judgements raised against them, ie Waistell v Network Rail.
