Common Winter Cress, Barbarea vulgaris, a plant that is in many wild edible field guides but your chances of finding it before it becomes too bitter is very slim, trust me it has a very strong taste. Medicinally, it was used as a blood medicine, cough medicine, stimulant, astringent and diuretic.
Keep your eyes and ears open and your powder dry
