This plant is weedy. We do not recommend planting it in Hawai’i.
The African tulip tree is the only species in its genus. It is grown in tropical countries worldwide and has become invasive in many areas, including Hawai’i, where non-native birds readily pollinate the flowers. The wind-dispersed seeds germinate readily and naturalize in low elevation, wetter areas throughout the Islands. This species has been cultivated ornamentally and in forestry for over a hundred years in Hawai’i. Further planting of African tulip tree should be avoided. Spathodea campanulata has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 14 (High Risk).
