Problem species? Identification & treatment please
I have an ever increasing and resilient plant (weed?) growing I need to get rid of. I has broad green leaves and stalks, pinky white underground shoots and and a deep red bulb. I have also dug up a root like ginger which is deep red again. Can anyone help me identify these, and give me thoughts on how to eradicate them.
I have used PlantSnap and got varying results.

Some people pay good money for it. It’s in my garden. Quite pretty when it flowers. A bit of a spreader but I just dig it out if it starts to get a bit bolshie.
Would love to see flowers.
I wonder if it is Bistorta officinalis???? Previously called Persicaria bistorta
Loves moist soil.

Here is a short video clip of the persicaria I have flowering but not sure what variety it is.
if people pay good money for this then I have found my fortune! The back of my garden is riddled with it and it’s difficult to dig out. I sprayed a clump with weed killer last week and so far it’s had zero effect! I’ll do some more research now I (you) have potentially identified it. Again, many thanks 👍🏻👍🏻
