| Identification | Mouse-ear Cress is readily seen in early to mid-spring. Flowers appear almost as soon as the plants break through the ground and continue as the stem grows 6 inches to 1 foot tall. The basal leaves are obovate or elliptic, taper to the stem, and generally lie on the ground. The stem leaves are essentially sessile, narrowly elliptical to linear. The flowers are small and white; the pods linear, round in cross-section. | |
