Mine do the same, it all depends on when they began growing, nothing to worry about. The blue ones leaves tend to stay above ground for longer than the white or pink.They are native to damp woodlands, so they do not want to dry out , desert style, but they do not want to be waterloggged either. Now is also the time to see if there are any seeds and to sow them fresh, as sson as they fall off the plant.

Thanks Owdboggy for your response. I read somewhere that Anemone nemorosa needs damp soil during the dormant period to allow the plant to continue developing. Under the trees in my woodland garden the soil dries out completely and I wonder if I ought to put the sprinkler on if this happens.

The soil in our Plum tree woodland border dries to dust and very little stays green over Summer, but the Anemones survive. I think it is up to you, if you feel they need a drink then water them, it will do no harm as long as they are not saturated.

Thanks for your input Owdboggy.
