What is this please?

Can anyone identify this and more importantly how do I get rid of it!?
It’s running wild?!

 

Looks vaguely like some kind of bamboo.

 

Many thanks for the advice. Can anyone suggest something that will kill this for sure? has anyone had experience of this and has got rid of it?

 

I've never had a bamboo problem, so can't really say what would be best to kill it.
Glyphosate should do it I would think.

 

The bamboo I had was clump forming and didn't spread like the one you have. I had it dug out as I don't like them.

Round Up which contains glyphosate probably won't touch it but I think SBK would kill it. Failing that something stronger like Gallup perhaps. They are all systemic killers and I've used all three.

Be careful to use any of these on a windless day, as they will kill or damage any plant they touch.

 

Thanks for all your advice

 

Please can anyone identify this little plant which has just started flowering? It is low growing. I can't remember it from last year It looks like a phlox flower but doesn't have the height.

 

Im no expert but my favourite flowers are phlox. I would say judging by the flowers and the leaves that it is a Phlox. Ive had a couple do what you said yours is doing when Ive moved them and they've sprouted babies where a bit of root has been left in the ground. I guess another clue is does it smell nice? Somebody else may tell you different.

 

Thanks @ThePlantAssassin - it does smell nice so I think it is phlox. I have lots of white ones so this makes a nice change.
