DESCRIPTION:
Sowthistles are among the most common weeds in farms and gardens in spring. They can be seen at any time of the year in mild climates, but commonly germinate from late fall to early spring with the highest numbers of mature plants present in spring and early summer. The sowthistle seedling has markedly stalked, almost spoon-shaped seed leaves, rounded at the tip. The seed leaves often have a grayish powdery bloom, but later leaves have only a few hairs. Later leaves have prickles or teeth along the margin with a winged stalk on the third or fourth and later true leaves. Flowers are yellow and mature into fluffy white seed heads. Stems are hollow and exude a milky juice when cut open.
