Watercress is a member of the mustard family, which includes many well-known leafy and tuberous vegetables such as collared greens, kale, turnips, and radishes, as well as many problematic weeds such as garlic mustard. It is widely cultivated and is the same watercress commonly used as a salad green. It is also used as a garnish for meats and other dishes where a peppery or pungent flavor is desired. Its peppery taste enhances many a salad or soup, and even tea.
Most US states have listed this species as invasive to wetlands.
