This sand-loving plant is also Arctic, and finds a place in the Pre-glacial deposits of Norfolk, and Interglacial beds at Hoxne, Suffolk. It is found at the present day in the N. Temperate and Arctic Zones, and has been introduced in the south. Sheep's Sorrel is found, everywhere in Great Britain as far north as the Shetlands, and up to 2500 ft. in Yorkshire. It is a native of Ireland and the Channel Islands.

Whereas the Common Sorrel is frequent enough in most fields and meadows, especially those that are moist and situated on clay soils, Sheep's Sorrel is a sand-loving species, growing on rocky knolls in or near woods, on heaths, and sandy wastes, e.g. warrens, and the seashore, as well as dry pastures at high elevations, and is said to be an indication of dry and poor soil rich in iron.
It is a tall, graceful plant with spear-shaped leaves which give it a characteristic appearance. The stem is single, unbranched, erect, smooth, the lower leaves spear-shaped, with lobes curved backwards, the upper ones more stalkless, and with an acid taste. The stipules or leaflike organs are torn and silvery.
