Thanks for your help, everyone. I think I've almost got everything identified. This one sprouted typo a couple of months ago. I couldn't find it on any of the weed websites and none of my friends knew. I just have a few of them that are growing in the same bed with the teasels and rhubarb. The other day when the sun was shining I noticed the leaves have transformed into seed pods. So now I'm thinking I better find out what it is before those seeds can get too far! The first pictures were taken a month ago and show the pretty blooms. The last two pictures showing the seed pods were taken a couple of days ago. Is this something I need to destroy to keep the seeds from spreading?
Wow that one was fast! Thanks! I thought there was something familiar about it. I've seen it dries in arrangements many times.
