Curly Dock
Rumex crispus
Smartweed-Buckwheat family (Polygonaceae)
Introduced from Europe, Curly Dock is now found across much of North America. Young leaves are rich in vitamins A and C, and are edible raw or cooked in small quantities, but the oxalic acid often in the plant can be injurious. Western Dock (R. aquaticus) is a similar species that has unbranched stems below the flower cluster and often heart-shaped leaf bases. Plant can be invasive.
