Mine is in part shade and I have never deadheaded, although I did snip a bloom stalk one year to try to harvest seeds for swapping, and
I don't have any seedlings. I enjoy the texture and pattern of the huge leaves, too. Just a great plant, IMO. I can't say that about oenethera,
evening primrose, though. I planted some pink evening primrose several years and have been pulling it out ever since. DON'T PLANT IT!
