Winter annual broadleaf
A winter annual weed of agronomic crops, pastures or roadsides. Leaves initially form as a basal rosette. Stem leaves are arranged alternately along the stem, are without petioles, and become progressively smaller up the stem. Leaves are highly lobed with the terminal lobe being much larger and more rounded than any of the lateral lobes. Stems are erect, thick, succulent, often tinged with red or purple, and may reach 3 feet in height. Many bright yellow flowers are produced at the ends of the flowering stems. Individual flower heads consist of yellow petals with a yellow center.
