Plume poppy (Bocconia frutescens)
Plume poppy is a shrub or small tree up to 6 m tall with very large, lobed leaves. It outcompetes native plants and can form dense infestations.
Profile
How does this weed affect you?
Plume poppy is a fast growing shrub or tree that can form dense infestations that:
- outcompete native plants
- compete with plants in eucalyptus plantations and orchards.
What does it look like?
Plume poppy is a branched shrub or small tree up to 6 m tall. It often has multiple trunks.
Leaves are:
- green on top and whitish on the underside
- large and can be up to 90 cm long, however they are usually 10-45 cm long and 4-20 cm wide
- deeply lobed with many lobes
- sparsely covered with small stiff bristles on the upper surface
- densely covered in fine hairs, especially along veins on the lower side.
Flowers are:
- purplish to greenish
- erect, oval shaped, with 2 joined sepals but no petals
- up to 1 cm long
- in dense clusters of up to 2000.
Fruit are
- capsules with a single seed
- grey when mature
- oval shaped
- about 1 cm long.
Seeds are:
- shiny and black, with a red fleshy covering at one end
- 5-7 mm long.
Branches are:
- up to 6 m long
- green when young
- brown and woody when older.
Where is it found?
In NSW, there has been an infestation near Taree in the Hunter Region. Plants were found in 2021 and it is likely that the original trees were intentionally planted as ornamental garden plants. A single plant has also been found on the Central Coast.
The plants have been destroyed and the sites are being monitored for any new plants. All new seedlings are destroyed.
Plume poppy is native to Central and South America and the West Indies.
What type of environment does it grow in?
Plume poppy grows in tropical, subtropical and warm temperate climates, usually in areas with at least 750 mm of rain per year. Plants can grow in full sun and partial shade but not full shade. Although plume poppy prefers well drained soil it has been found growing in a wide variety of soil types.
Plume poppy can grow in:
- woodlands, open forests and forest edges
- pastures
- orchids and plantations
- disturbed sites such as roadsides.
Maps and records
-
Recorded presence of Plume poppy during property inspections (Map: Biosecurity Information System - Weeds, 2017-2023)
These records are made by authorised officers during property inspections under the Biosecurity Act 2015. Officers record the presence of priority weeds in their council area and provide this to the NSW Department of Primary Industries. Records reflect the presence of the weed on the date of inspection.
How does it spread?
By seeds
A single plume poppy plant can produce over 300,000 seeds per year. The seeds can survive in the soil for decades. The seeds are spread by birds and water.

Control
If you think you have seen this plant call your local council weeds officer.
Prevention
Do not plant ornamental Bocconia species. Do not move any soil that could be contaminated by seeds.
Hand removal
Plume poppy is shallow rooted so small plants can be pulled out by hand.
Chemical control
Cut all of the stems low to the ground and apply herbicide gel to the remaining stump within 15 seconds.
Collect all fruit and burn in a site that can be inspected regularly for any sprouting plants. Alternatively contact your local council weeds officer for advice on disposal.

Biosecurity duty

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. |
| Hunter |
Regional Recommended Measure* (for Regional Priority - Eradication)
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. |
