Sow thistle, cerraja

Sonchus oleraceus


Also known as hare thistles or hare lettuces. They are annual herbs. All are characterized by soft, somewhat irregularly lobed leaves that clasp the stem and, at least initially, form a basal rosette. The stem contains a milky sap. Flower heads are yellow and range in size from half to one inch in diameter; the florets are all of ray type. Sow thistles are common roadside plants. Like the true thistles, sow thistles are in the family Asteraceae.
