Bloody Dock (Rumex sanguineus): Striking Red-Veined Foliage Plant

Bloody Dock: Dramatic Foliage for Moist, Sunny Borders

Rumex sanguineus, commonly called bloody dock or red-veined dock, is a taprooted perennial grown primarily for its spectacular foliage. Each lance-shaped green leaf is intricately etched with deep burgundy-red or purple veins, creating a stained-glass effect. In early summer, erect stems bear tiny star-shaped green flowers that age to reddish-brown, followed by dark brown fruit. Native to Europe, North Africa, and Southwest Asia.
