Ok, according to one report the little yellow wild flower is a horrible weed, (name still unknown) that will take over if allowed. The leaves are horrible as they stick to everything and will not come off of clothes and gloves even in the washing machine.
But - one man's flower is another man's weed. I only have one of the little yellow flowers. I have millions of tumbleweeds, and way to many devils claws, and other un-named weeds. As well as a surplus of marigolds. So for now I will keep the little yellow wild flower - weed.
