I'd pot them up and grow them on for a bit Dreeny. Put them in shade /part shade til they're established

Its up to you, they can go straight in the ground, or you can pot them up into larger pots, nurture them on for the summer, and then plant out early spring, once in the ground and they get going they will form very long roots, great for late colour and do equally well in a semi shade situation or in full sun, once they get going they can seed freely and be a little invasive in a nice way, julien.

O.K., pot them on it is. I have had some losses with plants because, I think planting out too soon instead of "potting on" and did not want to make a mistake with these healthy but fragile looking plugs..

Many thanks.

Just a little warning. I have been putting weedkiller on Japanese anemones for the last 8 years to try to get rid of them from where they have killed off everything else in their path. The weed killer has had very little effect on them and they are spreading further and further in the border, the lawn and the paths.

Oh, what a nuisance, how would you control their growth if starting again?

I would only ever plant them in containers.

depends on which varieties, some of the newer ones are much better behaved.

I have some that aren't spreading at all - they're barely growing. Most disappointing. :-(

Worst of all, we never actually planted these. They were here already or have self seeded without me noticing.
We have an alpine growing area which is supposed to look like a dried up river bed. I dug out the soil to a double spade depth and riddled the soil to remove the Anemone roots. That was 5 years ago. I noticed today that there is a new Anemone leaf in the middle of the bed.
Perhaps we have been unlucky and I am being a bit alarmist, but I would feel very guilty if someone's garden was ruined because I did not warn them.

Thank-u so much to everyone who answered my qurdtion, very much appreciated. I certainly have options.

The old very tall pink ones are very hard to get rid of but I am hoping that the more modern varieties like Honorine Jobert are not like that?
