What is this root?

Hi, we live in a rented property and there has previously been a 5 year treatment for knotweed in the garden. It's now finished so we've been advised we can dig the soil. However, I've just been clearing and found this root with some Sprouts coming off it. Does anyone recognise it as anything or think it could be knotweed again? I'm obviously reluctant to touch it anymore.

    Hi @Niamhtreacy and welcome to the forum :)

    I can't see what it is yet ... the leaves are too young ... but it doesn't have the very distinctive growth pattern of Japanese Knot Weed.   :)

  • @Dovefromabove it's not the best picture, the leaves are very small. The root they're attached too seems very large which is my concern. But that is reassuring, thank you.

    Definitely not knotweed.

    Possibly some kind of cow parsley like thing.

    It's not ground elder is it? It looks like the roots I had on mine (like bean sprouts).  There are some pics of it on my first post.

    Not Ground Elder, not from a root like that. Give it another week for those leaves to unfurl the repost.

  • Hi, an update on the root. The leaves have started to grow a bit. Not sure if anyone can tell what it might be?

    Looks like acanthus to me. A thug which spreads with runners when it's happy.

    I will stick my neck out and suggest Acanthus spinosus (I have shoots like that coming up near where I dug one out last Autumn. Most likely I left a few bits of root behind).
