Winter annual broadleaf

Cress, mouse-earA low-growing winter annual weed of fallow fields, no-till crops, pastures and roadsides. Basal rosette leaves occur on short petioles, are usually oblong or spatula shaped in outline with entire margins, and are covered in soft hairs above and below. Flowering stem leaves are alternate and without petioles, much smaller and more linear in outline. Flowers occur in clusters at the ends of the flowering stems. Individual flowers consist of four small white petals with a yellow center. The seedpods are small narrow capsules (siliques) about 1/2 inch in length.
