Abstract
  • Curly dock (Rumex crispus L.) is a perennial. It does not have creeping roots or rhizomes (Figure 1). Leaves are oblong to nearly lanceshaped, often 12 inches or more long, with wavy (crisped) margins (Figure 2). Erect, generally unbranched stems up to 5 feet tall are produced in spring and flower in summer. Broadleaf dock (Rumex obtusifolius L.) is similar to curly dock, but generally has larger, broader leaves, and one to three pointed teeth on the wing of the structure enclosing the fruit (the calyx; see Figure 3). In distribution, it’s more or less restricted to pastures and fields west of the Cascades, primarily in coastal counties.
