Barbarea vulgaris, also called as Bittercress, Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and Wound Rocket, is a biennial herb native to Europe.
During the autumn and winter, the plant has only a basal rosette of glossy leaves. As it bolts and flowers in the spring, it also has pinnately divided leaves arranges sparsely on the stem. The yellow flowers are borne in dense terminal clusters above the foliage in spring. It grows to about 8-32 inches.
Growing Conditions 
It is naturalised in many parts of North America as a weed. Winter Cress prefers moist, disturbed fields.
Greens are edible and have a similar taste to other mustard greens, but become sour when the plant bolts.
