Dooryard dock is a tall, sturdy perennial with large, wavy-edged leaves. It thrives around people in yards, roadsides, fields, pastures, shores and other disturbed ground. In summer it carries dense, almost leafless clusters of tiny greenish flowers that turn into dark brown three‑edged seeds which often remain standing through winter.
Did you know?
- It can regrow from broken pieces of its deep main root.
- The dry stems often keep their seeds into winter, and the seeds can blow far over snow.
About the species
Identification
Robust, upright plant to about 1.2 m. Stem firm and smooth. Lower leaves large (15–35 cm) with long stalks; upper leaves almost stalkless. Leaves long oval, usually 3–4 times as long as wide, with a blunt base and strongly wavy edges. Flowering stems carry dense, branched, almost leafless clusters of tiny greenish flowers in mid to late summer. Later, dark brown three‑edged seeds around 3 mm often remain on the dry stems. Compared with curly dock, the leaves are broader and less narrow-tapering. In Finland it flowers from July to September.
