Planted it about four years ago. It comes back and flowers reliably, but hasn't spread, and has stayed pretty much the same size. It is kind of lanky. Can't call it floppy, exactly, because the stems are wiry - but they go sideways as much as they go up. Beautiful clear, pale yellow, though. Wish it would spread!
