Rumex longifolius
Propagation: Seed - sow spring in situ.
Division in spring.
Cultivation: Succeeds in most soils but prefers a deep fertile moderately heavy soil that is humus-rich, moisture-retentive but well-drained and a position in full-sun or part shade[1].
Range: Europe, including Britain, from Scandanavia south and east to the Pyrenees, Caucasus and C. Asia.
Habitat: By rivers, in ditches and in damp grassy places[2].
Edibility: Leaves - cooked[3]. Harvested as they appear through the ground, they are eaten as a vegetable for their antiscorbutic action[4].

Medicinal: The whole plant, but especially the root, is alterative, astringent, cholagogue, deobstruent, stomachic and tonic[6][7].
Usage: Although no specific mention has been made for this species, dark green to brown and dark grey dyes can be obtained from the roots of many species in this genus, They do not need a mordant[8].
