Curled Dock

Description:

The mature plant is a reddish brown colour, and produces a stalk that grows to about 1 m high. It has smooth leaves shooting off from a large basal rosette, with distinctive waved or curled edges. On the stalk flowers and seeds are produced in clusters on branched stems, with the largest cluster being found at the apex. The seeds are shiny, brown and encased in the calyx of the flower that produced them. This casing enables the seeds to float on water and get caught in wool and animal fur, and this helps the seeds to spread to new locations.

Habitat:

Curled Dock is a widespread naturalised species throughout the temperate world, which has become a serious invasive species in many areas, including throughout North America, southern South America, New Zealand and parts of Australia. It spreads through the seeds contaminating crop seeds, and sticking to clothing.
