What is this plant?

GraylingGrayling Posts: 4

I have just noticed a tall vigourous plant that I thought might be Japenese Knotweed.  It has a similar stem (fleshy, hollow, in sections with red tinge) but the leaves are much smaller, spear shaped, with serrated edges.  It pulls up easily and has very shallow stuuby roots that area pinky/purple colour.

While I am confident it is not Jap Knotweed, I am concerened that it is an invasive species that could cause problems. The area it grows is very wet, really a lake that floods up in winter and dries back in summer.

    Does it have pink flowers that have a strong smell? It might be Indian or Himalayan Balsam. If so it's invasive.

    I tried to load a photo from my iPAD but the system did not seem to work so I copied and pasted into the message.  It doesn't show to me either - how do I adda photo?

    With an iPad you have to upload to a different site (eg picasa) and use 'external link' in the upload dialog after clicking the little tree.

    A trowel in the hand is worth a thousand lost under a bush.

    Grayling, can you look up himalayan balsam and see if that matches what you've got?

    That grows in wet places, is a major pest of waterways, but pulls up easily. You need to pull it all out before it flowers if that is the case.

    It's not a mess, it's a nature reserve.

    Thanks Bob, I'll try that.  Just seen a large clump in the wild area behind my garden. No sign of flowering yet.

    Just looked up Himalayan Balsam and have definite ID.  Looks like we'll be busy pulling them up over next few days - all the advice is to get rid of it before the seed pods form as they have loads of seeds in each pod and they explode, dispersing the seeds all over the place.  With us living next to a River and lots of wild space I suspect it si all over the palce so this is going to be a never ending task.

     Thanks to all who replied - I'll still try the Picasa upload to help others ID this plant.

    The first time I ever saw this balsam jobbie was in the 1960s. I walked past it in the late summer and the seed pods exploded in the most amazing way. Great fun when you are a teenager but not so much fun if you.re trying to get rid of it!

    Riverbanks are classic territory for balsam as fidget says. It's creeping in all over the country but doesn't get as much attention as knotweed. I hope you can get on top of it!
