How to identify Curly dock (Rumex crispus)
Curly dock, also known as Yellow dock
Curly dock is a perennial herbaceous plant known for its distinct wavy or curled leaf edges, which provide a clue to its identification. This plant typically grows to a height of 2 to 4 feet (60 to 120 cm) and develops a deep taproot. Its leaves are oblong-lanceolate, with the basal leaves larger, and they become progressively smaller up the stem. The green to reddish stems bear small greenish flowers in summer, which later turn into reddish-brown fruit. Curly dock's hardy nature allows it to survive in a variety of conditions, illustrating its adaptability and resilience.

Distinct wavy leaf margins aid in identification, characteristic of basal and stem leaves.
Tiny wind-pollinated flowers lack petals, with yellowish-green sepals forming a three-winged structure.
Dry capsules contain dark brown, 3-angled seeds measuring under 1/8 inch in length.
Hairless, ribbed stems are light to medium green, standing upright and reaching 1 to 3 feet in height.
Adaptable plant with deep taproot, growing to 2-4 feet height, green to reddish stems bearing small flowers.
The leaves of curly dock are distinctive with their very wavy margins. The basal rosette leaves can reach up to 1 foot (30 cm) across, while stem leaves measure about 6 inches (15 cm) long and 1 inch (2.5 cm) wide. Both stem and basal leaves are oblong-lanceolate in shape with a smooth texture and alternating arrangement along the stem. The pronounced wavy edges and oblong-lanceolate form are key identifying features.
Curly dock's flowers form in whorls within a panicle of racemes, each measuring about 0.5–1 inch (1.3–2.5 cm) long. Individual flowers are tiny, around 1/8 inch (0.3 cm) long, and lack petals. They feature yellowish-green sepals that take on a three-winged appearance and eventually turn brown as they mature. These flowers are wind-pollinated and do not emit any discernible scent or fragrance.
The stem of curly dock is hairless and prominently ribbed, giving it a distinct texture and appearance. It is generally a light to medium green color, frequently standing upright. The stem is slender but sturdy, typically ranging from 1 to 3 feet (30 to 90 cm) in height. It usually branches sparsely, and each rib is well-defined, offering a subtle tactile feature. This ribbed structure allows for easy identification among similar species.
The fruit of curly dock is encapsulated in a dry, brown capsule housing a singular seed. These seeds are dark brown in hue, boasting a unique 3-angled shape with each angle smoothly tapering to a pointed tip. The textural quality of the fruit is dry to the touch, bearing resemblance to a tiny, three-sided pyramid. The seeds typically measure just under 1/8 inch (about 3 mm) in length, offering a distinctive characteristic for identification. The mature capsules contribute to both the propagation of curly dock and its recognition in the wild.
