An annual wildflower/garden weed in Illinois. Base leaves are deeply divided w/ lobes and teeth; leaf size reduces further up thee stem. Flower clusters are terminal w/ numerous flower heads to 1" across. 12 to 20 petal-like ray flowers surround a butter-yellow disk. Found in low, wet woods, fields, and along roadsides.
aka: Butterweed.
