Description
Curly dock is a robust herbaceous perennial weed that produces a deep, yellowish taproot. The plant starts as a prominent basal rosette of long, crinkled leaves before sending up a tall, reddish-green flowering stalk that can reach up to four feet in height. In summer, it produces dense clusters of small greenish flowers that mature into rusty-brown, papery seed pods containing glossy triangular seeds.
Habitat
Disturbed soils, agricultural fields, waste areas, roadsides, pastures, and damp meadows. Prefers full sun to partial shade and moist, nutrient-rich soils.
Native Range
Native to Europe and Western Asia, but now widely naturalized throughout North America, Australia, New Zealand, and temperate regions globally.
