Japanese Anenome

Hi, Since recently moved into new house, lots of Japanese Anenome has appeared over large areas of garden, where we don't want it, including amongst newly planted beds and borders. Have tried poisioning it with strong plant/stump killers but it doesn't even wilt. Have tried digging it up but new shoots grow from the tiniest piece of brown root which is hard to spot. Please can anyone tell me how I might get rid of this plant. Thanks.

Hi Hippy, we also have Japanese Anemone which we introduced into our flower bed about 15 years ago - it would take over if we let it. I don't advocate the use of any type of killer, so about 5 years ago we dug up most of the flower bed and started again - and guess what - the Japanese Anemone grew back yet again. I do like the flowers, they are delicate and so pretty, but I just don't want a whole flower bed full of them. Now I have a weekly session pulling out leaves and as much root as I can.
It requires a lot of patience I'm afraid and you have to keep at it. Just carry on doing what you are doing.
That comment seems very heartfelt Ladybird - the voice of experience?
I am grateful that they spread in the sunken garden as ( apart from rhodos, azaleas, camellia, pieris and hydrangeas of various types which grow well) I have difficulty with perennials in that area.
We dug over a large flower bed in the centre of our patio in early spring - before any sign of the JA. Spent over £300 on shrubs/plants for the bed and planted them. Within a few weeks, JA reared itself... right through the root balls of the new shrubs!!! To remove the JA, had to dig up all the new shrubs and repot them in the original pots they came in. 4 of these have now died!! A complete waste of money. We have left the offending bed empty and dug it over twice, including sifting the soil, but it still comes up. There are similar areas around the garden where it is also spreading into the lawn. The flowers may be "delicate and pretty", but this plant is a garden thug (as described by RHS). We are at our wits end.
Snap! Just about managed to get rid of it from one place by leaving the soil empty for the last 6 years and putting Roundup on it every time a leaf appeared.
yes I have to agree that they are thugs. I value them under the tree in my back garden, where little else will flower once the tree is in leaf, but I made the mistake of planting some in a nice sunny border in my front garden. They are much too happy and I will have to dig them up and thin them out. They are very pretty at this time of year though and to be honest the rest of the plants in the border have run out of steam by the end of June. They sulk for about a year when first planted but once they get going there is no stopping them.
Verdun, my white and double pink ones don't spread much, rather they form large clumps.
I don't think my wild swan would enjoy damp shade. What's your opinion?
I don't know why they were advocating this plant on GW TV show last night, and why it's for sale at some many GCs at the moment!! On GW last night they were even showing people how to propagate it - you don't need to it spreads itself! Pretty flowers and long flowering period but is indeed very invasive. We were also at our wits end. We had two areas of the flower beds which were completely taken over. It is now about 2 years since we literally dug it all up and got as much of it out from the roots but it's still not gone. We had to even get rid of some of the soil and replace with new. It had invaded the paving, rockery and lawn - we have had to re-do that part of the lawn, the whole rockery and paving still needs to be done.
I have seen the massive thick runner going under the lawn - it was very big and it's still lodged there. It had strangled many other plants and we moved a hydrangea (see below) to set it free. the JA still pops up all over the place but not in such large quantities - and like yourself and GuernseyDonkey2 we are constantly having to pull out leaves and roots. I am not sure what the answer is sorry, it is very difficult to eradicate.
