Geranium sanguineum

 Geranium sanguineum, common names bloody crane's-bill or bloody geranium, is a species of hardy flowering herbaceous perennial plant in the cranesbill family Geraniaceae. It is also the county flower of Northumberland.

The genus name is derived from the Greek γέρανος ("géranos"), meaning crane, with reference to the appearance of the fruit capsule. The specific Latin name sanguineum refers to the red color assumed by the leaves in Autumn.

Geranium sanguineum is native to Europe and temperate Asia. It is widespread in most of Europe up to Caucasus. In the north-east of Ireland it is a rare garden escape.

The typical habitat of this species is grassland, sand dunes and open woodland on calcareous soils, including rocky slopes. It prefers calcareous soils with neutral pH, with low nutritional value, at an altitude of 0–1,200 metres (0–3,937 ft) above sea level.
