    Hi, my name is liam and I am looking for anyone who wants to get rid of their houttuynia or japanese knotweed, as I am trying to use fresh plants as medicine for my infection that have me disabled. Any help is appreciated, if you know where houttuynia grows, or where I can find herbicide free japanese knotweed. Thanks

    The usual one here is Bohemian knot weed, if that matters.

    I see tons of japanese knotweed, but even today I saw posters up saying they were using pesticides on it, glysophate or something I forget the spelling

    I saw Houttuynia cordata at Canadian Tire, the variegated one. Some is growing here, but 70 kilometers from Vancouver. Will check tomorrow, have been pulling it out.
    Glyphosate is an ingredient of the Roundup herbicide.

    There is knotweed growing in several easily accessible locations in northwest Burnaby, apparently not treated with any herbicide. Send me a PM if you are interested.

    I have knotweed in my garden, guaranteed herbicide free. You are welcome to as much as you want. I am in Vancouver on the west side. Send me a PM if this location works for you.

    Odds are you are seeing tons of Bohemian knot weed.

    Yeah and thanks I know lots about knotweed and it's problems but as a medicine their roots are invaluable. Herbal stores sell the root, which is silly because it's eveywhere.
    Houttuynia is harder to find.

    Yes, the links were more for other viewers, interesting plant.
    What parts of the Houttuynia are used ?

    The Arial parts, they have broad range antibacterial activity, not very popular yet amongst herbalists.

    I'm not sure how long it will take for new leaves to sprout here on the Houttynia, but you are welcome to some plants or leaves when they have sprouted.
    'Chameleon' is the variety noticed in the stores.

    That ISC page shows photos of Bohemian knot weed as Japanese knot weed, as is often the case - only the pictures showing plants with distinctively heart shaped leaves are presenting the true item. I also doubt the claim that zig zag stems are a distinctive feature for Japanese knot weed - the hybrid and the other parent in the cross also have stems that alternate directions between nodes (but maybe not as much, with that difference being what was meant).

    The general pattern here is for most patches of large weedy knot weed species to consist of the hybrid (Bohemian) knot weed, with the parents just being found here and there.

    Judging by the size of the leaves and the height of the stems my knotweed is Bohemian.

    Liam: for your purposes does it matter if it is Japanese or Bohemian?
