That looks right tlh, Thanks.
I'm a little puzzled about the color though. When I GOOGLE "images of Spanish Needle" just about all of the pictures are of white flowers with yellow centers. But the leaf and seed characteristics match my pictures perfectly. The yellow flowers that show up in the GOOGLE search seem to have long oval leaves with no lobes.
I wonder if deer eat this stuff. It's so prolific it would make a great cover crop.
