Orange Hawkweed (Pilosella Aurantiaca)
About Orange Hawkweed
Orange Hawkweed is a perennial species that reproduces via above-ground runners and rhizomes, seeds and, in some cases,
buds that sprout from the roots. It spreads by intentional and accidental human activities, wind, animals, and in contaminated
hay and soil. It has bright orange flowers with several flower heads in clusters atop each stem. The usually single unbranched
leafless stem contains a milky fluid, is 30 cm-120 cm (1-4ft) tall and covered in black hairs. The leaves are found at the base of
the stem in rosette formation and are hairy on both upper and lower surfaces.
How to Remove
- Dig out rosettes and their shallow roots in new, small infested areas or cut the heads off and burn when and where
- Take care not to spread any of the vegetative parts of the plant as re-growth from roots, stolons and rhizomes can occur.
Care must be taken not to break the roots and to ensure the entire plant is removed.
- Although mowing, before the flower goes to seed, may prevent seed set, it should be used with caution as it encourages
enhanced vegetative spread.
- Solarization can be used (cover with black plastic) followed by heavy doses of urea.
- Reseeding infested areas with native plants can help provide competition for hawkweed and encourage a healthy plant
- Place in heavy trash bags for transportation to a proper green waste disposal facility. DO NOT COMPOST fresh cut green
plants or roots. Disposal facilities: Salish Soils, Pender Harbour Transfer Station, Gibson’s Residential Green Waste Drop Off
- Alternative plants: Alpine Aster, Arkwright’s Campion, Blanket Flower, Carnations.
