|Spathodea campanulata P. Beauv.|
This showy, shade-tolerant, evergreen tree reaches heights of 25 m. It invades abandoned agricultural land and closed forest where the wind-dispersed seeds germinate rapidly. These seedlings continue growing, forming thickets from which a few saplings may reach the canopy. Adaptation to fire is unknown, and it has not been evaluated for biological control.
Tuliptree occurs in wet habitats from sea level to 1,000 m on all major islands. There are major infestations tucked away in almost every rain forest valley along the northern and eastern slopes of Kaua'i, O'ahu, and East Maui.
