Dock (broad-leaved) (Rumex obtusifolius)

Widespread - most plentiful on wet soils. Perennial.



Has large broad leaves and a taproot. Produces buds that turn a reddish colour.



Seeds are long-lived, so large banks of seed can build up in the soil. When dock-infested paddocks are cultivated, they are soon reinfested, both from seedlings and regrowth of roots. Sheep eat docks, but cattle and horses avoid them.
