The only plant that comes to mind is Geranium phaeum 'Samobor'. Here is a link that might be useful: Geranium phaeum 'Samobor'

I can't tell from the link to white avens if thats the first plant. not enough of the leaf shows on the picture to compare it. I'll look at some other databases maybe to see if there's a better leaf pix. I thought the second plant might be an astilbe - the leaves are so similar to my large astilbes, but these are so much shorter. I'll have to research and see if there's a low growing or creeping one. thanks for the help. oh and I think I might have figured out the pix thing - so here's another! Here is a link that might be useful:

I'd suggest removing them individually with shovel or spade. Would also consider posting to a list like Craigslist offering them free for the digging. Glad you don't want to use chemicals!

While the flower may look like the umbrella wort, the plant itself is nowhere similar. This is only about 8" high, sends out a vinelike stem and stays close to the ground until the stem gets longer. I'm stumped. I've sent requests to Plant Identification on Facebook and to Lady Bird Wildflower Center FB page and no luck. The flower is green, it doesn't open up another color and change to green.
