Horticulture/Barbarea vulgaris

Barbarea vulgaris, also called as Bittercress, Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and  Wound Rocket, is a biennial herb native to Europe.

Description
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.

Uses
Greens are edible and have a similar taste to other mustard greens, but become sour when the plant bolts.
