A bitter edible invasive weed in the mustard family that’s difficult to erradicate, so we might as well eat it. Hot, radish-like flavor similar to watercress. Not really hairy, it makes a wonderful spicy salad green. Little vertical stick-like seed pods stand upright surrounding tiny white flowers. Related to Large Bittercress (Cardamine amara ), and Wavy Bittercress (Cardamine flexuosa), which are also edible.
