What is this plant please

[PaulGallico]

Just bought these flowers. Does anyone know the name of the yellow plant at the top of the bunch. Thinking it would look great in a garden at this time of year when things are beginning to fade.

Goldenrod, AKA Solidago.

Thank you !

Don't try to grow in your garden.

In other parts of the world, however, the relationship is decidedly negative. Goldenrod—a remarkably adaptable group of plants—has taken over fields throughout Europe and Asia, putting native species at risk wherever they grow. Goldenrod can reach up to 2 meters in height, so they block the sun from reaching smaller plants. They are also prodigious reproducers, with each adult plant capable of releasing up to 10,000 tiny seeds which are easily dispersed by the wind. Finally, their roots also produce a group of chemicals that can inhibit the growth of other plants that surround them, a process called allelopathy. Those three factors alone have been enough to label goldenrod as some of the world’s worst invasive plants.

@KittyCatsby - blimey! - thank you.

I was coming to say the same, highly invasive!

Although apparently they are now breeding some better behaved ones for the garden.

Canadian goldenrod. There is a UK native Solidago, with larger flowers.

I have this. Despite pulling out loads of shoots in Spring it still multiplies mercilessly - and pops up in different parts of the garden (and in neighbours' gardens 😳

It is pretty and flowers as everything else fades.
