Helosciadium nodiflorum
Also called Water Celery, European Marshwort, Fool's Water Cress
Fool's watercress is a low-growing or creeping perennial of wet ground, ditches and shallow water, best grown in constantly moist or waterlogged soil. It is a wild herb whose key requirement is consistent wetness rather than fussy care.
Helosciadium nodiflorum (synonym: Apium nodiflorum), fool's watercress, is a flowering plant found in ditches or streams, as well as fresh and brackish-water wetlands native to western Europe. It is not poisonous to humans but it could be easily confused with the allegedly poisonous lesser water parsnip.
Helosciadium nodiflorum is common throughout England, Wales and Ireland but much less so in Scotland. It often grows with watercress in wet places. It blooms in July and August and is found in wet habitats including ditches, springs, fens and ponds. The species is also widely documented from brackish estuarine/salt marsh habitats.
Wild fool's watercress has been traditionally harvested and consumed in several Mediterranean countries, including Spain, Italy, Portugal and Morocco The edible young leaves and tender shoots can be used raw in salads, boiled, or used as a condiment in soups and other dishes.
