Please identify this plant

I think this looks like Lysimachia punctata (dotted loosestrife) rather than a goldenrod. The upright stems and dense clusters of small yellow flowers fit it quite well. It’s also a plant that can persist for years in neglected or partly shady areas.

If you can get a close-up photo of the leaves and individual flowers, that would make the ID much easier to confirm.

I suggest you personally take your phone and snap a couple of clear photos, then upload them later for fast identification:
1) lens.google/
2) botanapp.com/identifier/perennials

Covering a plant with heavy black plastic bags weighted down with stones or bricks will get rid of it or at least weaken it.

I would agree, it is loosestrife. I think it would be fine in a bed to itself in a corner of the garden but it totally wanted to dominate the bed I had it in and didn’t give other plants a chance. It took me years to get rid of it.

Google search does a great job. Just use the little camera icon on the search bar next to the microphone

Yellow Loosestrife died in my garden after a dry spell .
It needs moisture .
I forgot that it used to be attached to the bridles of horses to repel flies and can be burnt to repel insects in houses .
Another use - the flowers can be allowed to soak in water and the resulting liquid can be used to bath your naughty bits !
I don't know what the benefits are .
I can only guess !

If you mean the yellow flowers it's Yellow Loose strife. It grows abundantly in my garden but it's pretty and it's easy to pull out when there's too much.

It is called Solidago,

The one with variegated leaves is Alexander. There is also one with coppery brown leaves and yellow flowers called Firecrackers.

There is also a form with variegated foliage.

This looks more like 'Golden Rod' (Solidago) to me.
I had some from a friend, but it's gone...

Me too. Loosestrife it is.

Yes, yellow loosestrife. Had mine for must be 25 years now.

Large yellow loosestrife, not toxic to humans or pets. Would love some!!

fluttERBY123 Looks like a Skimmier

Gwyllt,it’s definitely not golden rod……not time for them yet……a few more weeks

The "Flora Incognita" app is pretty good as well.

I have one large clump and one small clump in my garden and love its brightness.

Do you have Google Lens - free to download if you don't.

Just open app, point at plant , piece of china, painting, shirt (almost anything) & VOILA - correctly indentified 99% of the time

Yes, Lysimachia, or Loosestrife. I admired it in the garden of one of DD’s neighbours so he gave me a clump and it has taken off. It has thuggish intentions but it’s so handsome and makes a lovely splash of colour, that I’m prepared to put up with it.

PlantNet says Loosestrife.

I love PlantNet - use it all the time taking photos of plants I like as I wander round then identifying them when I get home!

This made an appearance in my garden.
I left alone as I appreciated the yellow splash of colour .
It has since died off .
It's in the sane family as the Primrose and has some medicinal use in the right hands .

Yellow loosestrife is an invasive species here, and quite common. I think of it as a ditch plant, seen roadside and wouldn't think to plant it in the garden!

When you stop and look, it is actually quite pretty.

I'm another one voting for Yellow Loosestrife. Had it in my last larger garden. Bees, etc seemed to love it and it gave a vibrant splash of colour.

I think a bit differently and would hazard a guess at yellow rod many slightly different plants in the genus
