About
Delonix regia is a species of flowering plant in the bean family Fabaceae, subfamily Caesalpinioideae native to Madagascar. It is noted for its fern-like leaves and flamboyant display of orange-red flowers over summer. In many tropical parts of the world it is grown as an ornamental tree. It is a non-nodulating legume.
Although its country of origin was unknown, it had been in widespread cultivation for centuries. Finally, in 1932, a natural colony was discovered on the west coast of Madagascar by J. Leandri.
Where it grows
Delonix regia is endemic to Madagascar's dry deciduous forests, but has been introduced into tropical and sub-tropical regions worldwide. In the wild it is endangered, but it is widely cultivated elsewhere and is regarded as naturalised in many of the locations where it is grown.
