Japanese Anenomes

Im pretty sure there is already a thread about these plants somewhere but I have just spent a few hourse digging up pink anenomes from my garden.  The flowers are beautiful but I cant seem to control them in my garden.  I dont for a moment think I have seen the last of them but would be grateful for advice on how best to control them.  Failing that I will be hitting some sort of systematic week killer as they are becoming a real problem.  The white one I have doesnt seem such a thug.

    You coud dig a trench around what you want to keep and put plastic sheeting down to stop the roots travelling.

    A good idea from Lyn.

    I cut down into the ground a few inches beyond the plant with a spade to its full length every few weeks - that means that any new runners are easy to remove if they've managed to escape.

    Otherwise, a deep bottomless tub buried level with he ground's surface also works.

    Well, weed killer does not, that's for sure. Just discovered a new set of growth on one which has been treated with Glyphosate for the last 5 years. Must have had a gallon of the undiluted stuff on it in that time.

    Guess Ill just have to keep digging the bits up.  Has anyone had any problem with the white one or is it just the pink.

    One other thing does it have deep roots.

  • My Mum loves these plants, she keeps offering us some....so far we've resisted, I can't stand them.

     

    They are taking over every corner of her garden, they are everywhere & her garden is about 1/4 acre

    She offers them to anyone who visits her!!

     

    She's 85 and if they accept her offer, they have to dig them out image

     

    Most of hers are white although I think that a fair few started out pink.

    I find that the white one is just as much of a spreader once it's established.
