Lysimachia ephemerum seems to be considered non-invasive. Although it may not spread widely by seed, I wonder if anyone who has experience with it can tell me if it is like its cousin, L. clethroides, which, once planted, is almost impossible to be rid of as any little root left behind will grow. I'm currently growing it from seed but wonder if I dare plant it out!
Thanks.
I found it to be a very delicate plant... wish it had been tougher, as I think it's the most beautiful Lysimachia.
