Orange hawkweed (Hieracium aurantiacum)

Orange hawkweed

(Hieracium aurantiacum)


  • Orange hawkweed is a perennial plant native to the alpine regions of central and southern Europe
  • Bright orange, orange-red, or yellow flowers with several flower heads in clusters
  • Stems are usually single, unbranched and leafless; leaves are found at the base of stem in basal rosette formation (native hawkweeds will have true leaves all the way up their stems)
  • Stems are covered in black hairs
  • 0.3 – 1.2m tall

Consequences of invasion

  • Invasive hawkeed species can replace native vegetation in open, undisturbed natural areas
  • Reduce forage and threaten biodiversity
  • Outcompetes forage plants in hay fields and pastures

Integrated Pest Management Options

  • Fertilizer and soil fertility management
  • Minimize soil disturbance and promptly revegetate disturbed areas
  • Become Plantwise and learn about Grow Me Instead
  • Dig out rosettes and their shallow roots in new, small infestations
  • Do not spread any vegetative parts of the plant as regrowth can occur
  • Although mowing removes flower stems and may prevent seed set, it should be used with caution as it encourages vegetative spread
