Very common on the shore, and can extend up river banks for quite a distance inland.  Also occurs on mountain rock ledges and gullies.

Flower diameter c 5-15 mm

ID: Flowers with four widely separated petals, pods globular or egg-shaped, basal leaves about as broad as long.  Told from Danish Scurvy-grass by the upper leaves being unstalked, and usually clasping the stem.

Other features: Very variable.  The typical form is a large sprawling seashore plant.  Flowers usually white, but sometimes mauve especially in ssp scotica which has the base leaves not or only shallowly heart-shaped at base.
