Docks (Rumex spp. ), commonly known as smair dock, curly dock, kettle dock, butterdock, and cushy-cows, is a plant species in the Polygonaceae family. They are originated from Europe and now available in New Zealand, Australia, the United States, and others.
The three dock variants are Willow Dock, Western Dock, and Curly Dock[1]. The dock is typically found at the edge of forests, nutrient-rich soils, poorly drained buildings, and floodplains. It is common in acidic soils and in the highlands.
