If asked to name a single tree that’s helped shape the character of Brisbane, it would be the magnificent poinciana Delonix regia. In years gone by it was traditionally planted as a street tree and now enhances a lot of the city’s older suburbs.
The poinciana is native to Madagascar, and in Brisbane the bright orange flowers herald the coming of summer. They also signal the start of the storm season. http://www.abc.net.au/gardening/stories/s1755977.htm
Delonix regia is a species of flowering plant in the family Fabaceae, subfamily Caesalpinioideae. It is noted for its fern-like leaves and flamboyant display of flowers. In many tropical parts of the world it is grown as an ornamental tree and in English it is given the name Royal Poinciana or Flamboyant. It is also one of several trees known as Flame tree
In the Indian state of Kerala, Royal Poinciana is called Kaalvarippoo which means the flower of Calvary. There is a popular belief among Saint Thomas Christians of Kerala that when Jesus was crucified, there was a small Royal Poinciana tree nearby his Cross. It is believed that the blood of Jesus Christ was shed over the flowers of the tree and this is how the flowers of Royal Poinciana got a sharp red color http://en.wikipedia.org/wiki/Delonix_regia
The Royal Poinciana is most commonly propagated by seeds. Seeds are collected, soaked in warm water for at least 24 hours, and planted in warm, moist soil in a semi-shaded, sheltered position. In lieu of soaking, the seeds can also be ‘nicked’ or ‘pinched’ (with a small scissors or nail clipper) and planted immediately. These two methods allow moisture to penetrate the tough outer casing, stimulating germination. The seedlings grow rapidly and can reach 30 cm in a few weeks under ideal conditions.
Less common, but just as effective, is propagation by semi-hardwood cuttings. Branches consisting of the current or last season’s growth can be cut into 30 cm sections and planted in a moist potting mixture.
