Field Peppergrass

Lepidium campestre

 From the link ☼

Field peppergrass is most often found in meadows and wastelands, but will persist in turf. It acts as an annual in Southern regions and as a biennial in the North. Basal leaves are elongated, broad at the tip and deeply cut with rounded notches. They are covered with soft hairs which make them gray-green in appearance. When allowed to mature, leaves become spear-shaped and clasping on the upright stems. Flowers are inconspicuous, with four tiny white petals. Many spoon-shaped seed pods are formed after the flowers have bloomed. Field peppergrass is another member of the mustard family.
