This plant is weedy. We do not recommend planting it in Hawai’i.
This tree is invasive on many wet sites on all the Islands and is still rapidly spreading. It is commonly grown worldwide as an indoor house plant, and was introduced into Hawaii in the late 1800s. Seeds are spread by birds in forested areas. Some lei makers use the pink floral buds, using the term he’e (octopus) for them. Schefflera actinophylla has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 13 (High Risk).
Native to Northeastern Australia.
