Plume poppy (Bocconia frutescens)
Plume poppy is considered very invasive and is on the Hawaii State Noxious Weed List.
- Shrub to small (20 ft) tall tree
- Native to Central and South America, introduced to Hawaii as an ornamental garden plant
- Aggressive invader of dry forests. Forms dense stands that crowd out and compete with native plants, keeping them from growing
- Each plant can produce thousands of seeds that are particularly attractive to birds, which spread them long distances.
- Mechanical and chemical control of this species is difficult. Plants often resprout after control and persistence is required to completely control plume poppy.
- Kauai: Not present. Please contact KISC if you see this plant on Kauai.
- Oahu: Present, but not an OISC target. Landowners are encouraged to control this pest.
- Maui: Serious invader in native dry and mesic forests of East Maui with dense infestations from Kula to Kahikinui. It is not believed to be controllable or eradicable on an island-wide basis. Landowners are asked to control where possible.
- Molokai: None known.
- Lanai: None known.
- Kahoolawe: None known.
- Big Island: Infestations in Wood Valley, Kau Forest Reserve, Honomalino and Manuka on the Big Island.
