How to Control Japanese Anemone

Thank you for your responses. Why a previous owner of this place put them in, is beyond me. Still, it'll give me a lifetime of employment!!

 

I think you'd be better creating a separate space somewhere for the peony - sunny, with good soil, and then tackle the anemones if you don't want them @RowlandsCastle. If it's J. anemones you have, it may be difficult to clear the space well enough to allow the peony to thrive.
They do self seed. Well - they do here anyway. I've moved several seedlings - often a fair distance away from the original plant, and not attached in any way- as a runner would be. They like our conditions here too @NigelJ , but don't seem to become thug like in any way. I've grown them in several gardens without a problem.

 

They were popular at one time and in a larger garden a clump could be left to develop to a good size without being a problem.

 

Yes - if you combine them with earlier planting and/or bulbs, they give you a later display and also help to cover foliage that's dying back. I do that with mine. The height is also useful, so you can have them in behind lower planting.

 

Japanese anemones can be a nightmare. I inherited some in a previous garden which even spread under a low wall into next doors garden. I told my neighbour to dig them out on her side, I kept trying to keep mine under control but never got rid of them completely.
Regular decapitating, digging out of roots and weedkiller spraying helps but you have to keep at it.

 

Are all anemones ‘troublesome’ or just the Japanese variety? The plant below has recently appeared in an area of my garden- and Google suggests it’s a wood anemone. (I do live next to one)

It’s very pretty, so I thought I would leave it. Am I likely to regret that in a few years??

 

My Japanese anemones have never been a bother. If they start spreading a bit much I just dig them out.

I would keep that @KathM. It's pretty

 

They don’t become invasive here either, but that may because of my sandy soil. They have elegant stems and flowers which look good mingling with ferns in one of my dappled shady borders.

 

Those are fine @KathM - it's just the Japanese anems that some people find problematic.
They flower much later in the year

 

Poor unimproved clay in dappled shade puts manners on them.

 

@KathM I think you're lucky there because your plant looks "anemone centred" like a garden variety, not the plain ones you normally see in woods

 

Yes - the 'common' woodland ones are single flowered, so that will be a cultivated variety, as @CarolineL says. Perhaps a neighbour has some in their garden @KathM

 

Definitely not from any neighbour - they don’t do anything except grass. I live next to a tree lined gorge and if I look over my fence, I can see lots way down beside the burn at the bottom. This is best I could find on google. Will definitely keep now tho. Thanks all.
