Help! never seen anything like this....

I have this very starnge plant growing near my rockery - it is growing upright, dead straight against the garden wall. It grows very very quickly - grows in height by approx 2 inches over night. 3 in total have sprung up near each other. The stem looks very much like some sort of bamboo - in fact it looks like a broom handle! I have attached photos and hope you can help!

 

Hi Kay

I have a horrible feeling it could be Japanese knotweed. But I should wait for further opinions.

 

Have your neighbours got bamboo?

That sounds a more likely explanation, Chris, as the ends of the shoots don't look like knotweed.

 

What do the leaves look like?If you could put up a photo of the leaves then that might help with identification.

I have just Googled and found this and it does show the lower stems which look similar to what you have there.If it grows tall quickly then it could be the dreaded JK...

Hi Kandy

My next door but one neighbour had a lovely, luxuriant patch of knotweed in her garden which, thankfully seems to have been vanquished. At least for the time being. The stems are very much like bamboo but at the top you get a tuft of heart-shaped leaves which seem to be different from what Kay has posted, even before they've unfurled. But it is a little difficult to judge from the photo.

 

I've got a sneaking suspicion it might be Arundo donax.
Or a very vigourous Bamboo

Dont think its Knot weed

 

I've just had a look at my Arundo and although the third pic looks very like it the new growth doesn't.

 

It isn`t Japanese Knotweed, it`s a bamboo/grass of some sort.:gnthb:

 

Does the plant do any leaves ?
I think that would settle the bamboo - knotwood argument.
Personally I wouldn't want either.
If bamboo it might be slightly easier to get rid of. Knotwood - :(

 

Just done some googling on Bamboo shoots, it looks like that to me.

 

Knotweed leaves open virtually straight away.

 

yes they do, It looks very bamboo like as (Chris) Boghopper said.

So weed and feed wont work then:lollol:

 

It sounds like a lot of digging and swearing and sweating to me. Then a drop of Glyphosate.:flag:
