This is quite a common plant of streams and ditches where it will often spread so effectively as to partially block the flow of water. The plant has been known for centuries as one with edible leaves and it is also a source of vitamin C. Nasturtium officinale is a new name in New Flora of the British Isles (2010) by Clive Stace for a plant previously know as Rorippa nasturium-aquaticum.

Nasturtium officinale is common in England, Ireland and Wales and common around most of the coast of Scotland
