Hey all. My wife was given this by one or her co-workers. She was told it was watercress but the leaves look nothing like it. It grows in much the same way. When you crush the stem it has a mild peppery-lemon smell and tastes the same. Her friend had multiple types of edible greens growing close together. She just wants to know that it is indeed safe to eat. She ate some before and nothing bad happened. Just wondered if anyone has seen this before or know exactly what it is and can indentify it for us. Thanks in advance
