If you think this is a self set weed, it looks like Pilosella aurantiaca, there's a yellow one called Pilosella officinarum. Very pretty and liked by insects.
I have it but it doesn't flower often, it grows in my pasture grass 'lawn' so even though I like to leave it unmown in summer it might get cut back sometimes.
