An invasive weed that is pretty and I am leaving it.

My daughter Annette informed me that the plant I was curious about in last post is called redshank or commonly called lady thumb. It is a wild edible that is on the list of invasive weeds because it is not grass. She said in the middle of the leaf  is a purple to black shevronish mark that looks like a thumb print. Thanks Annette.  They are an invasive species I like and Genevieve likes to pick them and bring inside.

Looks like little beads on the stems, very colorful
