English name: Royal Poinciana or Flamboyant. It is also one of several trees known as Flame tree. Discovered in the early 19th century in its native Madagascar.
In India this tree is known as Gulmohar (Hindi and Urdu -‘Gul’ means ‘Flower’ and ‘Mohr’ is 'Peacock', thus the name suggests a spectacular show of color, like the extraordinary colors of a peacock's tail). It is also known there as Krishnachura (Bengali: 'crown of the Lord Krishna).
The flowers are large, with four spreading scarlet or orange-red petals up to 8 cm long, and a fifth upright petal called the standard, which is slightly larger and spotted with yellow and white.
