tarev - do you grow the species Brunnera? It sounds like it loves your pot. I started with that one and fell in love with the blue flowers and I was glad at the time that it was a tough plant. That being said, it has taken over a corner of the "wild" garden, acting like a real thug. It's on a dry slope and gets afternoon shade and seems to love it there (although I wish it didn't). Seedlings everywhere.
