Practical Weed Science for the Field Scout: Corn and Soybean
Shepherd's-purse (Capsella bursa-pastoris)
Winter annual broadleaf
A winter annual with a low-growing basal rosette growth habit and distinctive triangular seedpods. Seedlings have cotyledons that are round and narrow to the base. First true leaves begin to form a basal rosette; however, young rosettes take some time before the distinctive lobes become noticeable. Basal rosette leaves are lobed into triangular segments. The leaves are covered with hairs on the upper surface, especially in younger plants. Flowers are barely noticeable, small and white to greenish white in color, produced at the ends of the flowering stems. The seedpods occur alternately along the stem and are heart shaped to triangular in outline.
