With its round, shiny, dark green leaves and tiny white flowers, watercress (Nasturtium officinale), is easily recognised. It is cultivated throughout Europe as picante salad leaves and grows wild in Skopelos, where it  was first recorded by the famous botanist Dr. E Halacsy in 1894.

It requires slow-running water or seeping ground for its growth and the plants here were found along the edge of the culvert on the peripheral road.

The Greek name kardamo (κάρδαμο), which it shares with another plant; cardamon in English.
