Camel thorn is an erect perennial shrub found mostly in pastures and neglected areas.
Camel thorn has an extremely vigourous root system, that has been known to break through sealed bitumen roads and spread from one side to the other.
Camel thorn is an erect perennial shrub that grows to 1.5 metres high. The thorns are up to 4 cm long. Leaves are 5–30 mm long and 2–14 mm wide. The pea-like flowers may be pinkish purple to red and yellow and are 7–12 mm long. Seed pods are 8–28 mm long, up to 3 mm wide and constricted between each seed. Each pod has 1 - 8 red-brown seeds.
Camel thorn is mostly found in pastures and neglected areas. It occurs where there is a high level of moisture in the subsoil and also grows well under irrigation.
Camel thorn reproduces from roots and seed. The seeds germinate in spring and rapid root growth ensures establishment ahead of most other species. New shoots emerge from the roots each spring and most flowering occurs through spring, although it can extend through summer.

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 - Prevention)
Land managers should mitigate the risk of the plant being introduced to their land. Land managers should eradicate the plant from the land and keep the land free of the plant. A person should not deal with the plant, where dealings include but are not limited to buying, selling, growing, moving, carrying or releasing the plant. Notify local control authority if found. |
