Identification

  • It is at its most poisonous in late winter and early spring.
  • it is a member of the carrot family and can easily be confused with other edible plants of the carrot/parsley cfamily, which have similar leaves and parsnip-like roots. Online Encyclopaedia of the Umbelliferae (Carrot/Parsley) Family of the British Isles 
  • In  Spring, the plants usually have very few leaves and the creamy parsnip-like roots just visible. After a storm the roots are more visible. 
  • Do not do this test unless you are wearing gloves. All  parts of the plant poisonous.
    • The leaves have a strong unpleasant smell when broken (like acrid celery).
    • The stems are hairless, grooved and hollow, 
    • This is taken from Galloway Wild Foods which also has a good image of the definitive leaves
