Red-veined dock is a taprooted perennial with a rosette of leaves distinctively marked with deep red or purple veins. It is grown mostly as a foliage plant or ornamental vegetable, but it also produces erect stems of tiny, star-shaped green flowers that turn reddish brown. These are followed by dark brown fruit. Native to Europe, northern Africa, and southwest Asia.
