The water pepper probably comes from Asia and feels comfortable in wetlands, at the edge of the pond but also in normal garden soil.
The leaves (dried or fresh) can be used like pepper and are used in Asian cuisine. In soups and salads with fish and seafood, the pleasant spicy taste, which does not overlay the fine fish taste, is very much appreciated.
