Anemone sylvestris is a difficult plant to obtain once the early spring is behind us. Plants tend not to be "retailed" once they are beyond their season of interest and by the end of May this mid spring flowering Anemone has past its peak. I wish to use it all the time but it is never available.
I have very little experience with it an have little to offer. Experiment please. The only thing I know is that, like Japanese Anemone, it runs around and self seeds itself - but in my opinion, never enough. I love plants (that I like) that run, cover space, and colonize and area, taking care of the space for me.
Here, this image is a plant I moved to my garden last summer. I had to share a little plug from a clients house since I can rarely get it out of the nursery.
The images I've shared...
I couldn't decide which I thought was the best to use...
