The word "Wallcress" originated from Middle English "walcresse", which can be further traced back to the Old English word "weallcresse". "Weallcresse" is derived from the combination of two elements: "weall", meaning "wall" (referring to the plant's habit of growing on walls), and "cresse", which is a variation of "cress", an old term for "watercress". Therefore, the etymology of "Wallcress" suggests that it is a type of cress that typically grows on walls.
