ID of plant growing EVERYWHERE!

We moved into our new home in September and the garden was a bit of a wasteland. Rubble & rubbish everywhere. I cleaned it up, dug it all over, sowed grass seed and created some borders and a rockery. Very pleased with the end result, BUT there is this random plant that keeps growing literally all over my garden now, in the grass, in the rockery, everywhere. When I dig it up it seems like its sprouting from old choped up roots (I guess left in the ground from when I dug it all over?). Here are some pictures...






 Can anyone identify it for me please? It is a pest or should I let it grow? Will it look nice or not? Also need to know if its poisonous or anything as I have a little boy who loves to play in the garden. Thanks in advance!

    Bay Willow Herb? Lots of different types. They spring up all over our garden too. They can be spread by the wind. The flowers ate pink & the seeds head looks like cfluffy cottonwool.

    It is Rosebay Willowherb known in the US as Fireweed. Not poisonous but is a bit of a pest. Easy to pull up the plants to control it.

    If it is rosebay willowherb then it's a beautiful plant evn if it is everywhere!

    Definitely rosebay willowherb. Quite attractive spires of pinky purple flowers in late summer, but a real nuisance if you ever let it seed. Worth digging up when you spot it because it's quite large and will squash other plants.

    Seeds are very lightweight & can blow in from any waste ground/railway banks nearby.

    I end up nuturing the odd plant most years until I realise! J.

  • Brilliant! Thank you all so much for the info! As it grows quite tall I am going to dig it out of the lawn but leave it at the bottom and sides of the garden where I am also growing little patches of wild flowers so it should fit in quite nicely! To stop it spreading do I just dead head it before it turns to the fluffy seeds? Also, will it come back next year or would I have to let it spread some seeds?

    And if you're lucky you may get elephant hawk moths laying their eggs on it - beautiful!

    I'd dead had it to stop it seeding. It will come back from the same roots next year, so you don't need to let it seed.
