Common Name: dock, curly
Species: Rumex crispus L.
Bayer Code: RUMCR

Curly dock is a perennial weed with a thick taproot. Leaves grow mostly at the base of the plant and are lance-shaped with wavy or curly margins. Leaf blades are 6 to 8 inches long and 1 to 2 inches wide. The green leaves may be tinged with reddish purple. Curly dock seldom produces seed in maintained turf. When the plants grow unchecked, small greenish flowers are produced in clusters at the top of the main stems. Flowers become reddish-brown at maturity. The shiny, reddish-brown triangular seed is surrounded by three sepals.
