Leaves stalkless and turn brownish purple in autumn unlike Water-cress whose leaves remain green all year. |
Easily mistaken for : Water-cress but that stays green and does not turn purple in autumn, and also has shorter, wider and flattened seed pods containing a double row of seeds rather than the single row of Narrow-fruited Water-cress.
Hybridizes with : Water-cress (Nasturtium officinale) to produce a sterile hybrid called Some similarities to : Fool's-Water-cress but that belongs to the Umbellifer Family, Apiaceae. Not to be confused with : Winter-cress [another Cabbage Family plant with similar name]. Habitat includes growing in or by slow-flowing fresh-water streams or in mud, often in limy soils.
