 Gardening Tips


Poinciana

Family – Fabaceae
Genus - Delonix
Species - regia



Poinciana is a spreading decidious tree in the Fabaceae family and grows to 15m in height. It is endemic to the dry decidious forests of Madagascar where it is endangered. Poinciana requires a tropical to sub-tropical climate and in Australia can be found from the Northern Territory to South-East Queensland. As the tree ages it develops a large number of dead twigs and branches which become a hazard in the garden. It is also a dangerous tree for children to play in as the branches break easily. A CSIRO report for WWF – Australia in February 2005 lists Poinciana as one of the top ten most serious invasive weeds available for sale in the NT. It has also become a naturalised environmental weed in Western Australia and Queensland.
