Firethorn (Pyracantha species)
Also known as:
hawthorn
Firethorns are hardy shrubs introduced as a hedging plant. They form dense thickets in coastal and tableland areas of NSW.
Profile
How does this weed affect you?
Firethorns form dense thickets shading out native species and restricting movement of people and animals. They are common in coastal and tableland areas of NSW.
What does it look like?
Firethorns are evergreen spiny shrubs. They have different shaped and sized leaves on the one plant. Flowers are white on all species and they produce small round fruit.
Four species have naturalised in NSW. They are:
- Orange firethorn (Pyracantha angustifolia), which is up to 3 m tall with white hairs on the stems, narrow oblong leaves up to 5 cm long that are rolled backwards on the edges, and yellow to deep orange fruit 5-8 mm in diameter.
- Nepalese firethorn (Pyracantha crenulata), which is a shrub or small tree, with red hairs on the twigs, toothed leaves up to 6 cm long and 1 cm wide, and dark red to crimson fruit, 5 mm in diameter.
- Broadleaf firethorn (Pyracantha fortuneana), which has short spines and hairy young twigs, oval to spoon-shaped leaves up to 5 cm long and 1-2 cm wide, and bright red fruit, up to 7 mm in diameter.
- Asian firethorn (Pyracantha rogersiana), which is up to 3 m tall, and has white hairs on the young twigs, coarsely toothed leaves up to 4 cm long and 1 cm wide, and yellow to orange-red fruit, up to 4 mm in diameter.

Biosecurity duty
The content provided here is for information purposes only and is taken from the Biosecurity Act 2015 and its subordinate legislation, and the Regional Strategic Weed Management Plans (published by each Local Land Services region in NSW). It describes the state and regional priorities for weeds in New South Wales, Australia.
| Area | Duty |
|---|---|
| All of NSW | General Biosecurity Duty All pest plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable. |

Regional Recommended Measure* (for Regional Priority - Asset Protection)
Land managers should mitigate the risk of the plant being introduced to their land. Land managers should mitigate spread of the plant from their land. A person should not buy, sell, move, carry or release the plant into the environment. Land managers should reduce the impact of the plant on assets of high economic, environmental and/or social value. This Regional Recommended Measure applies to all species of Pyracanth. |
