Oddly I've never found a seedling here, but otherwise they grow well with no effort.
I found by accident how easily pieces of root grow into new plants. I moved one and it kept coming back. It was the source of several trades after that- it was a bad spot for it because it covered the side walk, so every couple of years somebody got a nice bleeding heart. That went on for several years, but I finally got all the root that last time.
